SCOM 2012 - IIS Discovery Problems

Ran into a problem recently where we were doing a discovery on several production web servers. Agent installed without any issues and was reporting back to SCOM as expected. The weird thing was the agent would not discover IIS. This happened on two out of the six boxes we were working with. Four of them came back compleetly normal, two didn't.

We did several things to troubleshoot like reinstall the agent, force a discovery and rebuild the health service state, all to no avail. Since all the servers were built around the same time the thinking was something was different about the two machines that were not working so we started comparing them. The answer was not redily apparent so we had to do some research.

As it turns out the IIS Admin Service (IISADMIN) was set to Manual. It needs to be set to Automatic in order for the discovery to take place. We switched it over to Automatic and both servers came back correctly in about an hour. Strange situation but we are glad we got it working.

More to come!
