I am having an issue with my Exchange 2003 Active / Passive cluster. I have two resource groups: "Exchange" and "Cluster Group". The exchange group has all the Exchange resources.
I found it in a state where the "Cluster group" is running on one server and the "Exchange" group on the other. I tried to fail over the "Exchange" group and its starts the process but fails on this error "Cluster resource 'Exchange HTTP Virtual Server Instance 100 (CHFOH-WS-EXCHVS)' in Resource Group 'Exchange' failed.". I then fails back to the other server.
