Hi There, We have an 2003 Exchange Server failover cluster on two Windows 2003 enterprise SP2. Everything was ok until I failover to server2 and then restart the server1. The cluster service on server1 keep failing/stoping. When I check the cluster.log file I see this error below. Server2 cluster service is running just fine and is the active node. Both server has ran 5+ year with no problem with failover.
2014/10/29-20:07:42.153 ERR [INIT] Unable to bind RPC to CDP, status 1703.
2014/10/29-20:07:42.153 ERR [CS] ClusterInitialize failed 1703
I look up error code 1703 = "The RPC protocol sequence not supported"
I have try to reset the tcp/ip and winsock using "netsh int ip reset" and "netsh winsock reset" and restart the server1. cluster service still fail to run and return same error code 1703.
I have check the registry of both server and protocol sequence are the same.
Rpc_Binding_Order = "ncacn_ip_tcp,ncacn_spx,ncacn_np,NETBIOS"
Rpc_Svr_Binding_Order = "ncacn_ip_tcp,ncacn_spx,ncacn_vns_spp"
