Interesting thing I came across today...
My Terminal server was working 100%... Try to log onto it a bit later... NAH not working.
Received the error "RPC Server is unavailable".
Now remember this is a Donkey of a server !!! Server 2003... Though I would love to just through it out of the Window and tell the client to buy a new damn server.. I cannot :(
I googled the hell out of this one. Got so frustrated because its the same answer over and over and over again...
Start RPC service
Check Time and Date settings
Fair enough if those are the common issues that need to be resolved for the error to go away and be able to remote into your servers, but none of those worked for me.
Quite stressful !!
Anycase I ended up stopping the below service and changing it to Manual from Automatic
and taaadaaaa SHE IS WORKING !!
I am a happy admin once again :)
