Hi all,
I have a server-1 which is join to domain A. I need to add a domain user from domain B to my server-1 local group. I keep getting "The RPC server is unavailable" error message.
But i try to use another server-2 which also belong to domain A and same network segment as server-1, i do not encounter this error while adding domain B user onto it.
The problematic server-1 is a Windows 2008 R2 SP1 server. It is install with IIS and MS SQL database 2008.
Just one thing i am guessing whether is it the cause of the problem. Before server-1 join to domain A, i did not disable windows firewall. I disable it only recently. Could this has cause the problem on my server-1?
