Repair windows after a virus

I have a client whose machine became infected by a virus. A bunch of services were created, the network connections was blank even though the server still has internet access, and no one could connect to the server. I started the server in safe mode and was able to clean off the maicious files and services. Now I'm trying to restore the network connections. The Netman service will not start. I get "could not start the Network Connections service on Local Computer Error 1083: The executable program that this service is configured to run in does not implement the service" If I try to view th service dependencies, I get "Win32: The executable program that this service is configured to run in does not implement the service"
Can anyone help? This is their only server and DC; rebuilding it will be a very painful option.

Considering how many places the virus managed to get it's fingers in... perhaps a system restore will be a good choice. If you have a restore point from some time before the virus, you can restore to that and fix almost all the things the virus changed.

Restore sounds like your best option,  However you may also want to run the command SFC
this is windows System File Check.  it will go through the system and make sure all system files hash properly and have not been corrupted by a virus.  Be prepared to have your windows CD on hand when running this command
SFC /Scannow

Open in new window

Do you have a KB article I can look over for the steps, and do you know if I'll need the disk?

You may not need the CD but in my experience most of the time you do.

however you can always skip files that need to be replaced off the CD and continue however you will not be running a full scan that way.

My client can't find her 2003 SBS CD. Does anyone know if I can run a repair using the 2003 server standard CD?

I'm going to try the repair, but I'm having more problems which I'm opening more questions for. Thanks.
