For some reason the "Microsoft Windows Desktop Base Operating Systems Management Pack for Microsoft Operations Manager 2005" has gone missing from the MOM Management Pack Catalog.

A query for "Desktop" for example should give you the "Microsoft Windows Desktop Base Operating Systems Management Pack for Microsoft Operations Manager 2005" management pack.  We are working on getting this MP back onto our catalog site.  If you need it now, you can get it HERE.
