Outlook 2007 Service Pack 2 issues

So we just had a very interesting outlook issue that it took a while to find the answer to. We noticed that we were unable to expand distribution groups to there individual email names. Then we noticed that we couldn't add accounts to our outllok clients. After more troubleshooting we found that it was only effecting computers with outlook 2007 service pack 2. Once we narrowed down the issue I started to do some reasearch. And I came across the following KB article from Microsoft: http://support.microsoft.com/kb/969519/. the article explained all of the errors that we were having. We used method 2 to modify the exchange server registry and everything went back to working correctly. Apparently the root of the problem was the exchange server set to use DSProxt instead of the Referal service, and after Outlook 2007 service pack 2 it can no longer use the DSProxy. Well I am ust glad we found the error. It took a while so I thought I would add another link to the solution.
