NLTEST returning RPC_S_UNKNOWN_IF
Ran into a case today where NLTEST was returning RPC_S_UNKNOWN_IF.
C:\Users\Administrator>nltest /sc_query:bradforest
I_NetLogonControl failed: Status = 1717 0x6b5 RPC_S_UNKNOWN_IF
C:\Users\Administrator>nltest /sc_reset:bradforest
I_NetLogonControl failed: Status = 1717 0x6b5 RPC_S_UNKNOWN_IF
I cranked up netlogon logging but nothing appeared in the log which was strange. I then checked the windows services that were running on the system and noticed that netlogon was stopped and set to manual.
That would explain it!
