I am getting the same errors. I am running Exchange 2003, BES 4.0. Last Friday I loaded Sp 1 (w/HF 1&2) (we were trying to fix the calendar problem, BB to desktop sync) however I started getting a lot of errors. Soooooo, we uninstalled BES (very painful), then tried to reinstall it. The MDS isn't working now (continous error), however, email is functioning properly. I tried to reinstall Bes 4.0 Sp1, but it failed. Any info would be greatly appreciated. Sorry for piggy-backing on your thread....but it sounds like we are having the same issue....
