Win2k3 SBS downloaded some automatic updates a few days ago. In the office i'm working in, we have a few licenses, and certainly more people were using the server for the past several months, years maybe. We were using it as the domain controller and the exchange/blackberry server.
However, once it downloaded the updates it began locking people out of exchange. We have since moved the domain controller over to a new machine, but people still periodically get locked out of exchange. Any ideas?
My first reaction would be to revert to a state prior to the updates. Next I would carefully read the MSKB articles associated with each of the updates to see if I could determine which specific update was causing this issue.
