Hi, I am running System Center Operations Manager 2007 R2 Version 6.1.7221.0 and I am running Exchange 2003 (one frontend server and 2 backend servers). I have imported the Exchange 2003 Management Pack 6.0.6702.0 to the SCOM and I have installed the SCOM agent on all three exchange servers. However, on my exchange frontend server I am getting some strange errors in the event log: 1: Duplicate Signature ID usage detected for STT Signature ID: 'SignatureID:[{6A6D6497-1813-46be-B9E8-FF4A871A4D86}]\{EEA6C379-C8A9-15B7-F07D-F17DE5C6B338}'. The STT Rule and monitor for this ID might differ in configuration - please reconcile the settings. Alternately, this Signature ID may already be in use. Assign a previously unused Signature ID for this STT Rule/Monitor. Module will be unloaded.

Can you tell me why I get these warnings and errors on this server and what I can do to get rid of them? Kind regards, Carl-Marius
