Exchange 2007 Update Rollup 6 - My Experience

On 12 Feb I blogged about Exchange 2007 Update Rollup 6 having been released and that it also includes a fix for the critical security issue that was published under Microsoft Security Bulletin MS09-003.

I have seen a lot of posts on the internet about problems experienced after applying this update, so I recently decided to apply the update to a non-production environment. Here are my experiences.

About the environment:

  • 2 x CAS servers in a NLB
  • 2 x Hub transport servers
  • 1 x CCR Mailbox cluster
  • All servers run Server 2008 with SP1
  • All servers are physical machines

 

The only "strange" thing I experienced was that the installer sits on "Creating native images for .NET assemblies..." for more than an hour.

After it does complete, and the servers are rebooted, everything seems to work perfectly.I had no problems with services not starting or OWA not working after applying this update.
