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.

Rename 'recycle Bin' To Whatever You Want

1. Start, Run, 'Regedit'.
2. Press 'Ctrl'+'F' to open find box and type 'Recycle Bin' to search.
3. Change any value data with 'Recycle Bin' to whatever name you want to give it ( ie, like 'Trash Can' or 'Dump' etc).
4. Press F3 to continue searching for 'Recycle Bin' and change wherever you come across 'Recycle Bin' to new its new name.
5. Repeat step 4 until you have finished with searching and changed all values to its new name.
6. Close regedit and hit F5 on desktop to see the new name on screen.

Note: As a good practice, always backup your registry before changing anything although changing 'Recycle Bin' name is a simple tweak and doesnt affect anything else.

Here are some basics maintenance tasks you can do today to start improving your computer's security. Be sure you make these part of your ongoing maintenance as well.

Closing Open Holes

       
By Ankit Fadia

With the spread of Hackers and Hacking incidents, the time has come, when not only system administrators of servers of big companies, but also people who connect to the Internet by dialing up into their ISP, have to worry about securing their system. It really does not make much difference whether you have a static IP or a dynamic one, if your system is connected to the Internet, then there is every chance of it being attacked.

This manual is aimed at discussing methods of system security analysis and will shed light on as to how to secure your standalone (also a system connected to a LAN) system.

Open Ports: A Threat to Security?

In the Netstat Tutorial we had discussed how the netstat -a command showed the list of open ports on your system. Well, anyhow, before I move on, I would like to quickly recap the important part. So here goes, straight from the netstat tutorial:

Now, the ??a? option is used to display all open connections on the local machine. It also returns the remote system to which we are connected to, the port numbers of the remote system we are connected to (and the local machine) and also the type and state of connection we have with the remote system.
