You did not give me much to go on but there are several possible scenarios\
1. Open Component Services console and Click on computers.Right click on My Computer and select Properties. Select the MSDTC tab and click on Tracing Options. Click in sequence: Stop Session, New Session, Flush Data,
OK, and OK.
Restart the DTC service.
if that does not help try this:
If you’re installing a DC which will have only a public interface, unbiding the “ms network client” and the “file & printer sharing services” from that nic will cause errors and prevent you from accessing things like the GPOs. You’ll also get errors listed in the event log usually from the SclgNtfy service with the event id 1002.
To get around this problem install the Loopback nic (listed in Add/Remove hardware, Network Adapters, Microsoft>Microsoft Loopback Adapter).
Next bind the ms net client and the file & print sharing to it, place it on the top of the connections list in Adapters & bindings.
You don’t need to assign it any ip info to this nic as the assigned address is sufficient to make everything work. Maybe for speed assign a private range ip.
Let me know how it goes!
