My Blackberry Enterprise Server for Microsoft Exchange 4.1.6 MR4 Bundle 105 running on Windows 2003 has stopped working. I get the following Event ID messages # 20185 #20301 #20265 and #20222. For the user trying to get BB messages. I made a permissions change yesterday on the inetsrv folder, around 12 noon, it stopped working around 3 pm. I have put the permissions back to the way they were and rebooted, but I still get these same error messages and nothing is going through. I personally dont know a thing about BB servers, this was dumped on me because the BB engineer is gone. I only made the permission changes because it was left as an instruction to do. Anyway, like I said the permissions are restored to their original state and a reboot was done, and I still am getting these errors and no BB mail is flowing. Any ideas where to start with this?
