Recover a Corrupted System File

If an essential Windows file gets whacked by a virus or otherwise corrupted, restore it from the Windows CD. Search the CD for the filename, replacing the last character with an underscore; for example, Notepad.ex_. If it's found, open a command prompt and enter the command EXPAND, followed by the full pathname of the file and of the desired destination: EXPAND D:\SETUP\NOTEPAD.EX_ C:\Windows\NOTEPAD.EXE. If either pathname contains any spaces, surround it with double quotes.

If the file isn't found, search on the unmodified filename. It will probably be inside a CAB file, which Win XP treats as a folder. Simply right-drag and copy the file to the desired location. In other Windows platforms, search for a file matching *.cab that contains the filename. When the search is done, open a command prompt and enter EXTRACT /L followed by the desired location, the full pathname of the CAB file, and the desired filename; for example: EXTRACT /L C:\Windows D:\I386\Driver.cab Notepad.exe. Again, if the destination or CAB file pathname contains spaces, surround it with double quotes.

Directions
Rapidshare traces the users IP address to limit each user to a certain amount of downloading per day. To get around this, you need to show the rapidshare server, a different IP address. You can do this one of multiple ways.

Requesting a new IP address from your ISP server.

Here's how to do it in windows:
1. Click Start
2. Click run
3. In the run box type cmd.exe and click OK
4. When the command prompt opens type the following. ENTER after each new line.


ipconfig /flushdns
ipconfig /release
ipconfig /renew
exit


5. Erase your cookies in whatever browser you are using.
6. Try the rapidshare download again.
Frequently you will be assigned a new IP address when this happens. Sometime you will, sometimes you will not. If you are on a fixed IP address, this method will not work. To be honest, I do not know how to do this in linux/unix/etc. If this works for you, you may want to save the above commands into a batch file, and just run it when you need it.
