Thousands of Events from Computers You Don’t Want to Manage

I did a search of all the servers in my domain and approved the ones I wanted to manage. Now I see that every unmanaged computer showed up in the 'All Computers Group' and all and the appropriate child groups that rule their piece of the world. My search yielded events showing up in the All Events for these unmanaged computers as well. In fact every night MOM does a scan, I get a thousand events for these unmanaged computers. I would like to stop seeing them and getting noise from them. Any ideas?

From the microsoft.public.mom newsgroup
I guess you had been using wildcard in the MCR list. As a first step check out your MCR for wildcards, and change them to 'equal'. In this way these computers won’t re-appear with the next scan.

Second, you can delete the *unmanaged* computer by selecting them, right clicking on them and choosing to remove them.

Another approach is to add MCRs for the unmanaged computers to exclude them as an exclude rule will override an include rule. If you include everything with a wildcard and then exclude the specific ones you don't want to manage, the end result will be only those computers you want to manage. The problem with this approach though is that MOM will try to access all the computers when using a wildcard, so if you have a *permission* problem on one computer it will give you an error message on the DCAM although you excluded this computer so there’s no escape.
