What are you doing if your computer password lost?
You lost your root password, and need to get into your root Account?
This is something-serious well we'll try to work something out.
You need to have physical access to the Server or computer.
What you will need to do, is a re-boot.

Ok, Now how do you do it.

1: First think up a new password.

2: Reboot the machine.

3: At lilo prompt type Linux 1 This will bring up a single user system.
The prompt will be something like: #

4: At the prompt after you are in type:
passwd root

5: Enter your new password at the prompts.

6: Reboot like normal This reboot will return the machine back to normal run levels.

or if you don't want to reboot, type one of the following:

init 3 (for console login, which is the default)
init 5 (for XDM login)

How to Speed Up Your Computer
( free up disk space )

Use Disk Cleanup to....

1- Remove temporary Internet files.

2- Remove downloaded program files (such as Microsoft ActiveX controls and Java applets).

3- Empty the Recycle Bin.

4- Remove Windows temporary files.

5- Remove optional Windows components that you don't use.

6- Remove installed programs that you no longer use.

Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.

To use Disk Cleanup

1. Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.
Disk Cleanup calculates the amount of space you will be able to free.

2. In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list. (If you have multiple hard drives you will have to select which one to scan.)
Choose the files that you want to delete.


3. Clear the check boxes for files that you don't want to delete, and then click OK.

4. When prompted to confirm that you want to delete the specified files, click OK.
Be sure to do this if you want to speed up your computer speed…
