AVG and a reboot caused loss of print capability and video drivers?

[MichaelS]

Hey all,

I just left a client's site earlier today, only to get a call this evening saying that after I installed AVG (which found 3 "Backdoor" trojans -- I cleaned those) on his XP workstation, upon rebooting, the monitor turned green and network printing stopped working.

Somehow the NVidia drivers got corrupted as an error popped up about nvcpl.dll and some missing libraries. A quick google search turned up that, that file belonged to NVidia, so I walked them through re-installing the video drivers. That fixed the green screen problem.

Now for the printing issue, the printer works locally, so I got them to tell me the name of the workstation that the printer physically attached to (its part of an AD), I asked them to goto the other workstation that they want to print from and run \\ComputerNameHostingThePrinter (real name replaced there)... It then popped up a message saying it couldn't connect because there was a duplicate name on the network (I can't remember the error off the top of my head). I ended up telling them that i'll drive over tomorrow morning at 8am to re-share the printer and re-map the printer.

I should mention that i'm not the original admin that set all this up, and unfornately the company that set this rig up didn't provide them with any documentation about the network topology or the services.

What I was wondering was if anyone else had any strange issues with AVG and XP on a AD setup? On another machine in the office, I tried creating a *local* account and logging into that to resolve some other problems -- in which case a whole pile of drivers were corrupted.. I ended up rebooting and logging into the domain, in which all the driver issues went away.

Regards,

Michael
