Active Sync issues

[wdaniels2007]

My Touch pro had to be hard reset and now I can't seem to sync it with my work exchange server. Other than reloading it, nothing has changed. Getting Support Code:80072f78. I googled that, and its saying something about check server address and proxy, but believe me those are correct and not mistyped on the device or computer. The password, server and username is correct. I really hate active sync 4.5, it is very tempermental. I assume everyone has had this issue at one time or another syncing their device to their pc. If anyone can provide any insight, I would appreciate it.
