Kudos to Bhargav on the above script - I use this to get all my build numbers and rollups and can definately recommend it. It should be in the Scripts directory by default!
The fast way to check for the version of the installed rollup is to look at exsetup.exe/exsetup.com file version on the server.
FYI the link for Update Rollup 2 for Exchange Server 2010 SP1 is pointing to the wrong KB article.
Daniel, thanks, fixed!
This method doesn't work with Rollup4 for Exchange2007 SP3 - build 83.6 is shown instead of 192.1
