When running System Center Operations Manager 2007 you may notice the following event:
Event Type: Warning Event Source: OpsMgr Config Service Event Category: None Event ID: 29106 Date: Time: User: Computer: Description: The request to synchronize state for OpsMgr Health Service identified by "5209bd53-3cf6-dd12-af0d-7f872b995f76" failed due to the following exception "System.Runtime.Remoting.RemotingException: Failed to connect to an IPC Port: Access is denied.
This can occur if the OpsMgr SDK Service and the OpsMgr Config Service are running under different credentials.
Make Sure the OpsMgr SDK Service and OpsMgr Config Service are configured to run using the same credentials.
Please refer the KB http://support.microsoft.com/kb/936220 for How to change the credentials for the OpsMgr SDK Service and for the OpsMgr Config Service in Microsoft System Center Operations Manager 2007.
Hope this helps,
