generic host error

[Guest khaled azzaz]

Hi

I have a windows 2003 SP2 server as a member server that has exchange server

2003 installed on it. For some reason the system files were over-written by

some installation. that caused a generic host error by some DLL files and it

wil not allow me to see the netwrok. I tried to replaced the DLL files with

no success, I tried to re-install SP2 for windows server 2003, that is when

this installtion indicates that some system files were repalced by different

version. but, the SP2 installation stoped saying that RPC services is nopt

runing, eventhough it is runing.

 

how can i check which files were replaced and how do i correct them back?
