Can\'t install ethernet on dell optiplex 280 displays rpc server unavailable

[Guest]

when i try installing Ethernet controllers, i am given 'rpc server' not available. what should i do?

Is it a network card or the one which is onboard?
Try the below from the RUN command on Windows - START.

regsvr32 netshell.dll
regsvr32 netcfgx.dll
regsvr32 netman.dll

Reboot the computer.

If still persists, do the below from START - RUN - CMD

Reset TCP/IP stack to installation defaults, type: netsh int ip reset reset.log

Reset WINSOCK entries to installation defaults, type: netsh winsock reset catalog



If that doesn't help, try this small utility . .

Also check if after you install SP3 you had this issue, if yes try to unistall it for a test and see if it works fine.

Hope this help!
