I was helping a disabled friend to remove viruses from his computer. I updated his antivirus to AVG2012 and it detected several infections. After virus removal the computer was unable to acquire an IP address from the network. When I checked the connection properties I was unable to check them all because there was a blank window containing a message to the effect that Windows could not display them because Windows Management Instrumentation was corrupted.
I used the XP SP3 installation CD and the command line:
rundll32.exe setupapi,InstallHinfSection WBEM 132 %windir%\inf\wbemoc.inf
to rebuild the WMI, and this was successful up to a point because I was then able to look at all of the connection properties.
But still no IP address acquisition!
The ADSL modem PC activity light is on and occasionally flickers. The lights for DSL and Internet connection are on and steady. But nothing comes back from the modem to the computer.
I would appreciate some help.
