Updated System Center management packs Active Directory and Exchange 2003 that provide less false or noisy alerts.
There are several good updates and fixes here…. I recommend you download, test, and update these MP’s ASAP.
In the Exchange 2003 MP – there are still several noisy Self-Tuning Thresholds present…. so I still recommend you go through these according to my previous blog post on them: http://blogs.technet.com/kevinholman/archive/2008/03/19/self-tuning-thresholds-love-and-hate.aspx If you have already created overrides for these – no worries…. as they will still apply correctly once you update the MP. This is the beauty of these sealed MP’s, and overrides in different unsealed MP’s: very little fear or risk of updating your core MP versions from the vendors. Much easier to stay current without impact, compared to MOM 2005.
