IPSEC service fails on Windows 2003 domain controller

DilbertW01 asked
Last Modified: 2012-05-05
I have a Windows 2003 Standard server as a single domain controller for my domain.  I have been having the IPSEC service failed to start on the server periodically.  The Event log has the following:

Event: 7023

The IPSEC service terminated with the following error:
Only one usage of each socket address (Protocol /  Network Address / Port) is normally permitted.

The server seems to be pretty much dead in the water as for doing its normal roles.  DHCP is not allocating addresses.  A ping to the server is not returned.  I can't connect a network drive.  Etc.

This server does NOT have the Cisco VPN client on it.  I have read numerous sites that have shown a problem with it that generates this problem.  It's not the case with this.

I am looking for any suggestions as I have not had much luck finding anything else that might be the cause.

If you check your event log, are you getting the Event ID 4292 along with 7023.
