system
2
Problems 1 thru 4 solved. Quite a while ago in my desire to lock down my system and feeling I had no need for RPC, I renamed RPCSS.EXE to RPCSS.EXF thereby disabling the RPC :
Renaming it back, then rebooting, corrected the problems.
This brings up a question; can I once again kill RPC or does this service always need to be available for AVAST.
