Part 1: What is Update Rollup 5? What does it is for?
Part 2. How to install Update Rollup 5?
Part 3. Oppps and OMG! (Troubleshooting after a problematic rollup install)
Before you download and install, may I first share some of our gotchas in installing a rollup update like this and most of it we got from the You Had Me At EHLO blog, you may want to read their posts first before doing anything. Also browse thru their links and make sure that you have read everything before doing so. That I may say my biggest mistake on this update, that we have done this just before the Holidays! We are rushing to get out of the office and saw a new update on the Windows update service. Say, after being so confident on windows update, we treated the RU5 as just another update. After that part 3 happened (we are already out of office when we found out!)
Based on the system requirements, the gotchas that we saw on this rollup is that it only Supports Exchange Server 2007 SP1 (not the RTM version) and any Interim Updates for Exchange Server 2007 must be uninstalled prior to installing this update rollup.
To install, you may download the update thru the Microsoft download service: http://www.microsoft.com/downloads/details.aspx?FamilyId=652ED33A-11A1-459C-8FFE-90B9CBFE7903&displaylang=en or thru windows update.
The update is very straight forward and If you do everything by the book and plan this update, you may not get any error like this that we had:
The next part is the errors that we encountered and how we fixed it.
