Internet Protocol TCP/IP missing from Network Properties

I have tried to reinstall the protocol and I get an error that the file is missing.
It used to be there. I am running XP Pro sp2 (pre-install), Intel pro wireless 3945, AVG (recent scan clean), Comodo firewall, Spyware blaster, all updates.VMware server (the guest bridged internet connection used to work, the nat still does)
I just uninstalled comodo Boclean as this is the most recent change to the system, but I still get the error. My connection still works but I want the protocol.

I need help repairing the file so I can reinstall the protocol.

Thanks

 

Okay, this is wher I am so far.
I came across MS kb 299357 that resets the Internet Protocol but that didn't work.

I found this;
You have a bad registry entry.

Start, Run, regedit

Click on this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
Scroll past the folders to show this value: DevicePath

The value should be %SystemRoot%\Inf and of type REG_EXPAND_SZ

I checked into this and my key value is about half a page long. I'll post if anyone's interested.

I found another thread that suggested to uninstall the wireless drivers. I did that and received and error that the driver could not be uninstalled, it was needed for reboot. I restarted the computer and 'new hardware was found, installed but would not work properly.'
I tried installing the manufacturers (sony) driver and was told that I would have to manually uninstall the driver in order to downgrade as the driver currently installed was a newer version. Still not working.
I tried the Intel 3945 abg driver. I received an error that the install failed because the system could not find the file.

Any ideas will be much appreciated.

Oh, forgot to mention I can't install any thing in the network properties, ie. Client,... not just Internet Protocol.

 

You can't install tcp/ip in xp because its a core compent, so you shouldn't be able to reinstall it either, the command to reset it should be.
netsh int ip reset resetlog.txt
netsh winsock reset (sp2 only)

Thanks for your post Colemanguy,

I tried that command and nothing changed. My reset log was the same as the one on the link you gave. I was also missing Network Monitor Driver, AEGIS Protocol and WLAN transport from my Wireless Network Connections Properties.

I restored an image of my OS and this has fixed the problem. This thread is closed.

Thanks again Colemanguy
