I'm having a problem with a W2k3 server which is running Exchange 2003 SP1.
Last night it updated to W2k3 SP1 over our SUS system - obviously this shouldn't have been allowed as there are issues between SP1 and Exchange.
Not surprisingly, Exchange no longer works. The Information Store service quits with error code 0.
I have uninstalled the service pack but this has not resolved the issue.
The error in the event log relates to DCOM and says as follows:
Access denied attempting to launch a DCOM Server. The server is:
The user is SYSTEM/NT AUTHORITY, SID=S-1-5-18.
A search of the registry suggests that the server in question is Microsoft Exchange Property Mapping Interface.
Can someone tell me how to set the correct permissions for this? At present I cannot even find it in dcomcnfg! DCOM is not something I am familiar with.
Thanks in advace for any help.
