Lost internet/network connection

Greetings. I'm helping de-bug a friends Win 2000 machine. She had
over 200 viruses on it. AVG Free now reports no viruses.

Before the virus scan and repair, I had internet connectivity via
cable, through a router. After the repair I can't connect to
anything. I tried changing the network card, and tried going
wireless, which reported connection to the access point but "the
internet cannot be found".

The virus log files reports the following files as "change":
kernel32.dll
wsock32.dll
user32.dll
shell32.dll
ntvskrnl.dll

I'm wondering if one of the viruses corrupted one of these files, and
the repair made it unusable. I've tried Windows repair from the CD,
(there is no repair disk) and tried re-installing using the current
directory. I'm trying to avoid a complete re-install of the operating
system. Booting to safe mode with networking doesn't work either. I
tried booting using debug mode but it locked the machine up.

For what it's worth, when it boots, it throws up a windows explorer
window at the winnt directory, and when it shuts down, I get an error
window reporting that the lsass.dll is having some kind of problem.

I'm wondering if copying the above noted files to the system off the
cd would help?

Any help here would be greatly appreciated, thanks.

If you have LSASS issues - you have BIG problems - if they don't go away when internet connectivity is restored, you should format the machine - LSASS is the security system in NT based machines.
