Change The Icons Of Drives

Change The Icons Of Drives

All the Xp users would have been bored by the boring icons in their My Computer panel which are adjacent to the Hard disk drives(C:,D: or whatever drive letter you have).
Here is a simple tweak by which you will be able to change this monotonous icon to anything you like, even your own Picture if you wish You can put any image in place of one which I have shown, even the picture of your favourite celebrity or your dream caror your own Picture.
Here are the steps you need to follow:
1.First of all the picture you want to use should have .ico extension(if you already have a pic with .ico extension proceed to step 2).Most of the pictures we normally use have extensions like .jpg,.bmp,.png..gif etc, so you first need to convert them to one with .ico extension.This is simple.Just go here and put your original image in the 'Source Image 'section,then click on 'Generate Favicon.ico ' button to get your image with .ico extension.
2. Now go to My Computer.Suppose you want to put this icon in place of your original C: image.
Double click and enter C: .Paste your .ico image file in it. Also create a new text file and in it type the following lines:
[autorun]
ICON=favicon.ico
Remember that 'favicon.ico' in the second line is the name of your image file.If you have an image file with .ico extension by the name of 'abc.ico',then use that in the second line in place of 'favicon.ico'.
3. Now rename this text file as ' autorun.inf ' (without the quotes).
Important Note: How do I rename my text file as autorun.inf ?Ans.Go to Tools->Folder options. Under the View tab uncheck the 'Hide extensions for known file types'.Press apply. Now rename your text file as 'autorun.inf'.
4. Now restart your Pc.You are done. Check out the cool new picture you have just added in your my computer panel.

How To Do Windows Server 2008 Istallation Step By Step



Windows Server 2008 Installation

Follow These Steps For Installation

1. Insert the appropriate Windows Server 2008 installation media into your DVD drive.

2. Reboot the computer.

3. When prompted for an installation language and other regional options, make your selection and press Next.

4. Next, press Install Now to begin the installation process.

5. Product activation is now also identical with that found in Windows Vista. Enter your Product ID in the next window, and if you want to automatically activate Windows the moment the installation finishes, click Next.

If you do not have the Product ID available right now, you can leave the box empty, and click Next. You will need to provide the Product ID later, after the server installation is over. Press No.

6. Because you did not provide the correct ID, the installation process cannot determine what kind of Windows Server 2008 license you own, and therefore you will be prompted to select your correct version in the next screen, assuming you are telling the truth and will provide the correct ID to prove your selection later on.

7. If you did provide the right Product ID, select the Full version of the right Windows version you're prompted, and click Next.

8. Read and accept the license terms by clicking to select the checkbox and pressing Next.

9. In the "Which type of installation do you want?" window, click the only available option – Custom (Advanced).

10. In the "Where do you want to install Windows?", if you're installing the server on a regular IDE hard disk, click to select the first disk, usually Disk 0, and click Next.

If you're installing on a hard disk that's connected to a SCSI controller, click Load Driver and insert the media provided by the controller's manufacturer.
If you must, you can also click Drive Options and manually create a partition on the destination hard disk.
11. The installation now begins, and you can go and have lunch. Copying the setup files from the DVD to the hard drive only takes about one minute. However, extracting and uncompressing the files takes a good deal longer. After 20 minutes, the operating system is installed. The exact time it takes to install server core depends upon your hardware specifications. Faster disks will perform much faster installs… Windows Server 2008 takes up approximately 10 GB of hard drive space.

The installation process will reboot your computer, so, if in step #10 you inserted a floppy disk (either real or virtual), make sure you remove it before going to lunch, as you'll find the server hanged without the ability to boot (you can bypass this by configuring the server to boot from a CD/DVD and then from the hard disk in the booting order on the server's BIOS)
12. Then the server reboots you'll be prompted with the new Windows Server 2008 type of login screen. Press CTRL+ALT+DEL to log in.

13. Click on Other User.

14. The default Administrator is blank, so just type Administrator and press Enter.

15. You will be prompted to change the user's password. You have no choice but to press Ok.

16. In the password changing dialog box, leave the default password blank (duh, read step #15…), and enter a new, complex, at-least-7-characters-long new password twice. A password like "topsecret" is not valid (it's not complex), but one like "T0pSecreT!" sure is. Make sure you remember it.

17. Someone thought it would be cool to nag you once more, so now you'll be prompted to accept the fact that the password had been changed. Press Ok.

18. Finally, the desktop appears and that's it, you're logged on and can begin working. You will be greeted by an assistant for the initial server configuration, and after performing some initial configuration tasks, you will be able to start working.

Configuring a Windows Server for RADIUS Authentication

This Help topic provides instructions for users who wish to configure a Windows 2000 Advanced Server or Windows Server 2003 to provide RADIUS authentication. It includes steps for configuring the Internet Authentication Service (IAS), and for creating users in Active Directory. Policy Manager has been designed to work with a RADIUS server for authentication. The IAS implements the RADIUS protocol, and provides authentication of users connecting to the network via LAN, virtual private network (VPN), and dial-up technology.
It is recommended that you begin by reading the Policy Manager Authentication Configuration Guide for general authentication instructions prior to following the steps here. Windows 2000 Advanced Server and Windows Server 2003 users should follow the steps in this topic, instead of the Installing and Configuring the RADIUS Server section in the Authentication Configuration Guide.
The recommended sequence for performing the configuration is listed below. When you have completed these instructions, refer back to the sections Configuring RADIUS in Policy Manager and Testing Authentication in the Authentication Configuration Guide for instructions on how to use Policy Manager to configure authentication parameters on your devices, and verify that the users created in Active Directory can authenticate to the network.

	NOTE:	The following instructions assume that you already have IAS installed on your computer.

Instructions on:

Configuring Active Directory

When using CHAP protocol, the "password reversed encryption" option must be enabled. You can enable this option globally for all users in the domain, or for a specific user. To enable this option globally:

Select Start > Programs > Administrative Tools > Active Directory Users and Computers.
In the Active Directory Users and Computers window, right click on your domain and select Properties.
In the Group Policy tab, select "Default Domain Policy" and click Edit.
In the Group Policy window, navigate to Password Policy in the left-panel Tree view: Computer Configuration > Windows Settings > Security Settings > Account Policies > Password Policy.
Right-click on "Store password using reversible encryption for all users in the domain" and select Security.
In the Security Policy Setting window, select the "Define this policy setting" checkbox and the Enabled radio button. Click OK.
Close all applications and restart the computer, and log into your domain.

To enable this option for a specific user:

Select Start > Programs > Administrative Tools > Active Directory Users and Computers.
In the Active Directory Users and Computers window, right-click on the user and select Properties.
In the Account tab, check "Store password using reversible encryption." Click OK.
Close all applications and restart the computer, and log into your domain.

	NOTE:	The Windows 2000 Advanced Server Troubleshooting IAS Installation guide states: "After you enable reversibly-encrypted passwords in a domain, all users must change their passwords before they will be able to authenticate against the domain."

Configuring Internet Authentication Service (IAS)

	NOTE:	Install the latest service pack, which is available at the Microsoft website, before configuring authentication for Windows 2000 Advanced Server or Windows Server 2003. The following instructions assume that you already have IAS installed on your computer.

Specifying RADIUS Port Numbers

Use the following steps to specify the RADIUS authentication and accounting port numbers.

Select Start > Programs > Administrative Tools > Internet Authentication Service. The Internet Authentication Service window opens.
Right click on "Internet Authentication Service (Local)" and select Properties.
In the RADIUS Tab (for Windows 2000 Advanced Server) or the Ports Tab (for Windows Server 2003), enter 1645 in the Authentication field and 1646 in the Accounting field.
Click OK.

Adding RADIUS Client Devices

Follow these steps to add RADIUS clients (Policy Manager devices, not end users) to the server.

In the Internet Authentication Service window (Start > Programs > Administrative Tools > Internet Authentication Service), right click on the Clients folder (for Windows 2000 Advanced Server) or the RADIUS Clients folder (for Windows Server 2003), and select New > Client.
Enter a Friendly Name and Protocol and then click Next.
Enter the IP address of the RADIUS client and select a Client Vendor (i.e. RADIUS Standard).
Enter a shared secret. A shared secret is a string of characters that will be used to encrypt and decrypt communications between the RADIUS server and the device (RADIUS client). Without the shared secret, the server and client will be unable to communicate, and authentication attempts will fail. The shared secret must be at least 6 characters long; 16 characters is recommended. Dashes are allowed in the string, but spaces are not. Be sure to write the shared secret down, as you will be adding it to the RADIUS client devices later.
Click Finish.
Repeat until all of your Policy Manager devices have been added.

Adding a New Remote Access Policy

Follow these steps to add a new Remote Access Policy. A Remote Access Policy is a set of actions which is applied to a group of users that meet a specified set of conditions.

	NOTE:	For information on configuring end user VLAN ID attributes (in compliance with RFC 3580) to be used in conjunction with VLAN to Role Mapping, refer to your device firmware and RADIUS server documentation.

In the Internet Authentication Service window (Start > Programs > Administrative Tools > Internet Authentication Service), right click on the Remote Access Policies folder and select New > Remote Access Policy.
Windows 2000 Advanced Server: Enter a Policy friendly name and then click Next.
Windows Server 2003: Enter a Policy friendly name, select the "Set up a Custom Policy" radio button (as opposed to selecting the Wizard), and then click Next.
Follow these steps to add a condition. For example, to add a Windows Group condition:
1. Click the Add button to open the Select Attribute window.
2. Select "Windows Groups" and click Add.
3. Click Add in the Groups window.
4. Select a domain group (i.e. Domain Users) and click Add. Click OK.
5. Add more groups if needed in the Groups window. Otherwise, click OK.
6. Click Next.
In the Permissions window, select "Grant remote access permission" and click Next.

Add a User Profile for users who match the conditions you have specified:

Click the Edit Profile button to open the Edit Dial-in Profile window.
In the Authentication tab, select the appropriate authentication methods.
In the Advanced tab, remove all parameters, such as "Server-Type" and "Framed-Protocol" and click Add to add a Filter-Id attribute.
In the Add Attributes window, select "Filter-Id" and then click Add.
In the Multivalued Attribute Information window, click Add.

In the Attribute Information window, enter the attribute value:
Enterasys:version=1:mgmt=su:policy=[role]
where [role] is the role name to be applied to this user.

	CAUTION:	Include :mgmt=su in the string only for users who should have administrative privileges and the ability to telnet to devices and/or use local management on devices when authentication is enabled. For other users, leave it out.

Click OK to proceed through the windows and Finish.

Registering the IAS

Follow these steps to register the Internet Authentication Service in the Active Directory, which enables IAS to authenticate users in the Active Directory.

In the Internet Authentication Service window (Start > Programs > Administrative Tools > Internet Authentication Service), right click on the "Internet Authentication Service (Local)" and select Register Service in Active Directory.
Click OK.

Stopping and Restarting the IAS

After completing the above steps to configure the Internet Authentication Service, you must stop and restart the Service.

In the Internet Authentication Service window (Start > Programs > Administrative Tools > Internet Authentication Service), right click on the "Internet Authentication Service (Local)" and select "Stop Service".
Right click on the "Internet Authentication Service (Local)" and select "Start Service".

Creating Users in Active Directory

Use these steps to create users and specify user permissions.

Creating a User

Create a new object for each user who will be authenticating.

Select Start > Programs > Administrative Tools > Active Directory Users and Computers. The Active Directory Users and Computers window opens.
Right click on the left-panel Users folder and select New > User.
Proceed through the windows, entering the user name, password and other relevant information. Click Finish.

Specifying User Permissions

The steps for specifying user permissions are different depending on whether you are using Windows 2000 Advanced Server or Windows Server 2003. Windows 2000 Advanced Server
The steps to specify user permissions depends on your domain operation mode. There are two domain operation modes in Active Directory: Mixed Mode and Native Mode. In Mixed Mode, user permission is specified in the User Properties window. In Native Mode, user permission is specified in the Remote Access Policy that is configured in the Internet Authentication Service. To change the domain operation mode, consult the Microsoft Windows 2000 Advanced Server documentation for guidance.

Mixed Mode:
1. Right click on a user and select Properties. The User Properties window opens.
2. In the Dial-In tab, select either the "Allow access" or the "Deny Access" radio button in the Remote Access Permission (Dial-in or VPN) section.
3. Click OK.
Native Mode:
1. Right click on a user and select Properties. The User Properties window opens.
2. In the Dial-In tab, select the "Control access through Remote Access Policy" radio button in the Remote Access Permission (Dial-in or VPN) section.

How to make a Cross Over Cable Step By Step

Introduction
This document shows how to properly construct a Crossover network cable. This cable can be used to directly connect two computers to each other without the use of a hub or switch. The ends on a crossover cable are different from each other, whereas a normal 'straight through' cable has identical ends. Their uses are shown in the following diagrams.

Crossover cable use

'Straight Through' cable use

Typically the ports on a hub are MDIX ports. This allows the machine at the other end to utilize its MDI Port (which is what typically a NIC card uses) without the need for a crossover cable. When I say that the ports on the hub are MDIX ports, what I mean is that one of the functions of the hub is to automatically perform the crossover functions, which are required to properly align the cables with each other. When no hub or switch is used, your cable itself must physically perform these crossover functions.

To expand on this a little, when using a hub or switch, the Transmit wires on the workstation need to be connected to the Receive wires on the hub; likewise, the Receive wires on the hub need to be connected to the Transmit wires on the workstation. But if you remember what we stated earlier - cables which are run from PC to Hub are 'straight through' type cables. This is because the hub is providing the required crossover functions internally for you. Thus, when you connect two machines together without the use of a hub or switch, a crossover cable is required - because both 'ends' are essentially the same - a NIC Card. The crossover function must take place somewhere, and since there is no hub or switch to do it for you, the cable must.

Now that we know what a crossover cable is for, let's talk for a few about types of cabling. The two most common unshielded twisted-pair (UTP) network standards are the 10 Mbit (10BASE-T Ethernet) and the 100Mbit (100BASE-TX Fast Ethernet). In order for a cable to properly support 100 Mbit transfers, it must be rated Category 5 (or CAT 5). This type of low loss extended frequency cable will support 10 Base T, 100 Base-T and the newer 100VG-AnyLAN applications. Other types of cabling include Category 3 which supports data rates up to 16 Mbps, and Category 1 which only supports speeds up to 1Mbps. The cable we are about to make is considered Category 5, and will work on both 10 Mbit and 100 Mbit systems, assuming all components used (cables and jacks) are rated for Category 5.

What you need
Cable - Be sure the cable(s) you are using is properly rated for CAT 5. It should state clearly on the jacket of the cable, what it is rated at. One option that you have when selecting your cable is to use a pre-made normal 'straight through' cable, and simply whack off one of the ends, and replace with a new "Crossed Over" end. For the purpose of this article, though, we aren't going to go that route. We are going to make the whole thing from scratch - using bulk CAT 5 cable.

Keep everything within hands reach of you...

Connectors - Crossover cables are terminated with CAT 5 RJ-45 (RJ stands for "Registered Jack") modular plugs. RJ-45 plugs are similar to those you'll see on the end of your telephone cable except they have eight versus four contacts on the end of the plug. Also, make sure the ends you select are rated for CAT 5 wiring. There are also different types of jacks which are used for different types of cabling (such as Solid Core wire). Make sure you buy the correct jacks for your cabling.

Crimper - You will need a modular crimping tool. My advice on what brand to get? Well, I really don't have a preference at this point, but make sure you buy a good one. If you spend about 40 to 50 bucks, you should have one that will last ya a lifetime. Spend 10 to 20 bucks, and you might be able to make a few cables with it if you're lucky. You definitely get what you pay for when it comes to crimpers!

Stripper - No I'm not talking about what Spot had at his bachelor party, I am talking about a tool to strip the ends off the wires you pervert! There are several specialized tools, which can be used to strip the jackets off of cabling. If you do not have access to one of these tools, cautious use of a razor blade or knife should work just fine - but keep in mind if you go the razor blade / knife route, extra special care must be used as to not damage the wires inside the jacket.

Cutters - You need a pair of cutters that will allow you to cut a group of cables in a straight line. It is very important that all the wires are the same lengths, and without proper cutters, this can be a difficult task.

Doing the deed
You now know what crossover cables are used for. You know why you need one. You also know what you need to make one, so I guess we're ready... First thing you will want to do it cut off the appropriate length of cable that you will need. Be sure that it is plenty long enough. If you screw up, and don't cut it long enough, you will have to start all over, and you will not only waste you time, but cable and the RJ-45 ends as well. If you are pulling this cable through a wall, or ceiling, make sure the pulling is completed first. It is much more difficult to pull a cable with the ends already on it. So you have all the parts, you understand the concepts, and you have your cable, lets get started!

Baby steps...

1) - Start by stripping off about 2 inches of the plastic jacket off the end of the cable. Be very careful at this point, as to not nick or cut into the wires, which are inside. Doing so could alter the characteristics of your cable, or even worse render is useless. Check the wires, one more time for nicks or cuts. If there are any, just whack the whole end off, and start over.

2) - Spread the wires apart, but be sure to hold onto the base of the jacket with your other hand. You do not want the wires to become untwisted down inside the jacket. Category 5 cable must only have 1/2 of an inch of 'untwisted' wire at the end; otherwise it will be 'out of spec'. At this point, you obviously have ALOT more than 1/2 of an inch of un-twisted wire, but don't worry - well take care of that soon enough.

3) - Up to this point, things have been pretty easy. Things will get a little bit tricky here, but don't worry, we'll get through this together. We are at a point in this article where a decision needs to be made. You need to decide which end of the cable you are making at this point in time. If you are making your cable from scratch like I am doing while writing this article, you have 2 end jacks, which must be installed on your cable. If you are using a pre-made cable, with one of the ends whacked off, you only have one end to install - the crossed over end. Below are two diagrams, which show how you need to arrange the cables for each type of cable end. Decide at this point which end you are making and examine the associated picture below.

your cable to look like this) Crossed over end wire pattern

Begin to untwist the twisted exposed wires on your cable. Use caution so that you do not untwist them down inside the jacket. Once you have all the wires untwisted begin to arrange them in the proper order based on the pictures above. This stage can be a pain in the ass, especially some of the middle wires. Once you get all the wired arranged in the proper order, make sure your wire cutters are within reach then grasp them right at the point where they enter the jacket. Make sure you keep them in the proper order! Grab your cutters now. Line them up along your prepared wires about 1/2 inch above the jacket. Be sure at this point that you are both 1/2 inch above the jacket, and that your cutters are aligned straight across the wires. You want to make a clean cut here - also make sure you don't let go of that jacket / wires!

4) - Don't worry. From this point forward things get a lot easier. Grab your jack, and begin to slide the wires into the jack. Once you get to the point where the jacket begins to enter the jack things might get a little tough, but just have some patience and hold onto those wires. It will fit in there just fine. Once it is in as far as it will go the wires should extend almost to the front of the jack, and about 3/8 of an inch of the jacket will be inside the jack. Like the pictures below.

5) - Grab those crimpers - because not all crimpers are exactly the same your pictures may not match exactly what you see below. Be sure to keep a good grip on that jack and the cable. Insert the jack into the crimper. It should only go in one way, so you don't have a whole lot to worry about inserting it. Begin to compress those crimpers. You will more than likely hear a clicking sound. Keep squeezing. If you try to let go to early, nothing will happen. They will not release. Keep going until they stop clicking / stop moving all together. At this point, you should be able to let go of the jack, and the crimpers. The crimpers should release now leaving you with a crimped jack. If the crimpers do not release, you probably are a wimp and didn't press hard enough. Go ask your mom to help you at this point. She can probably finish what you started.

Insert the jack into the crimper Crimp it! Crimp it good!

6) - It's time to examine what we have done. If you look at the end of the jack (distal), you should see that the copper connectors should not be pressed down into the wires. Toward the back of the jack (where the jacket meets the jack) it should be crimped securely holding the jacket / cable in the jack. If something has gone wrong, don't worry, its not the end of the world. Grab those cutters, and just whack the whole jack off and start back at step 1 (a pain in the ass I know, but its better to have a cable that works, than to spend hours trouble shooting your PC trying to figure out why you can't see the other machine). If everything is cool, all you have to do now is make the other end of the cable (unless you are using a pre-fab cable and have whacked one of the ends off), so go back to step one, and make the other end now.

In closing
You should now have a fully functional CAT 5 Crossover cable. It's a good idea to label it as such, especially if you have a lot of other cables lying around. So what are ya waiting for... install the cable and test it out. If it doesn't work, double-check the ends. There is always a possibility that you have overlooked something. If so just whack the bad end and make new one. Remember the more jacks you install, and the more cables you make, the easier it gets. It's really not that hard to do, the first time is definitely the most difficult.

Here are a few other things to keep in mind...

Maximum Cable length for including connectors is 100 meters (or about 328 feet)

Do not allow the cable to be sharply bent, or kinked, at any time. This can cause permanent damage to the cables' interior

Do not overtighten cable ties

Do not use excessive force when pulling cable through floors, walls or ceilings

Do not use staples to secure category-5 cable, use the proper hangers, which can be found at most hardware stores
