On my exchange server i've had this recent event log entry come up in my Application event viewer:
Event Type: Information
Event Source: IAS
Event Category: None
Event ID: 5050
The description for Event ID ( 5050 ) in Source ( IAS ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: EXCHANGE.DOMAIN.co.uk, DOMAIN.
And this entry appears every 30mins or so.
I have tried to open the log on a couple of other computers using the AUXSOURCE flag, but i still get the same message and nothing different.
Any idea what is causing this message and how i would go about correcting it?
