Good day.
We have 2 TMG 2010 servers working in NLB cluster. When we are opening "Network Load Balancing Manager" on any TMG server we receive the error message "the RPC server is unavailable" (it's about another node in cluster).
I've tried to add access rule which allows RPC (all protocols) between TMG nodes. But it didn't help. My next step should be disable RPC filter, but I can't understand which negative effect could be happened from this action.
Can anybody explain (better give the official link from technet) what could be wrong after disabling RPC Filter?
Perhaps there are another possibilities to solve this problem (we don't see another node in NLB snap-in, only local node)?
