If you have password protected a USB drive or partition on your computer and have since forgotten the password, you will need to completely erase the drive.

Erasing and reformatting the drive will remove any password protection, software and data on the drive preventing you from accessing the drive.

The process is simple using Window's Disk Management utility.

Log into the computer as the administrator.

Open the Windows Start menu, select "Run," type "Compmgmt.msc" and click "OK." In Windows Vista and Windows 7, simply type the command into the "Search" field.

Select "Disk Management."

Locate the password-protected drive.

Right-click it and select "Delete." Confirm the action.

The drive will be erased and become unallocated free space.

To open the set up page of the router of the router , one of your computer should be able to go online through the router.
It could be a wired computer or wireless computer.
If it is a wireless computer then make sure that the computer is connected to your own wireless network.
Do not change any wireless settings on the router using a wireless computer.
OK ! Now you have a computer online through the router and you want to open the set up page of the router.

First step is check the IP address of the computer.
Check the IP address and the Default gateway on the computer.

For Windows XP

START ==> RUN ==> type in cmd in the RUN box==> click OK or Hit ENTER . You will see a black window that is a command prompt . In the black window type in " ipconfig " ==> and Hit ENTER on your key board .

For Windows Vista and Windows 7

click on START ==> type in cmd in the start search box ==> enter ==> you will see the black window. Type in " ipconfig "you will see a lot of information. Try to find out the local area connection IPv4 address .

Note down the Default gateway number.

For MAC OS

Click APPLE icon in the right top corner of the computer. Go to System Preferences ==> go to Network ==> you will find the option Built in Ethernet or Airport whichever is connected. If you go to that you will find the Ip address and router Address.

The default gateway is the IP address of your router.

This IP address of the router will be used to open the set up page of the router

Now you got the IP address of the router.Open the Internet Browser ( Internet Explorer, Firefox, Safari )

In the Address bar of the browser Type the IP address of the router.

Do not type http:// or www just type in the IP address only.

It will ask you for the user name and the password of the router.

This is the User name and the password of the router and NOT the wireless password. On a wireless router, there are 2 passwords. One is to access the router and the other one is for the wireless network.

For most of the routers the default password will be " admin " . for some routers the default password is " password ". For Linksys router the default password is admin and no user name.

On the controlled pc you must open administrative tools - services and make sure telnet service is started and set to automatic.
On the controlling machine, open a dos window and type "telnet computer-name" or "telnet ip-address" when prompted enter username and password that is valid on controlled pc, at that point you can run many dos command line commands and programs. Make sure that controlled pc has passwords for all accounts, otherwise you open a big security hole.
