I am running SBS 2011, with all updates applied.
I get the following error EventID 1008
Unable to register the MSExchangeAB RPC interface. Failed with the error code The endpoint is a duplicate (1740).
Netstat dump with processes below:
TCP 0.0.0.0:6001 0.0.0.0:0 LISTENING 7056 Microsoft.Exchange.RpcCli 7056 MSExchangeRPC TCP 0.0.0.0:6002 0.0.0.0:0 LISTENING 4148 spnsrvnt.exe 4148 SentinelProtectionServer TCP 0.0.0.0:6004 0.0.0.0:0 LISTENING 568 lsass.exe 568 kdc, Netlogon, NTDS, SamSs
I have seen other posts that say this is to do with Global Catalog, however it is a DC as it is Small Business Server and therefore must already be a GC.
What could I start checking to resolve this?
