So, I made a bunch of my users mad today when they all the sudden couldn't get their email, printers, or network shares because I inadvertently restarted our Exchange server while working on some changes. How did it happen? Automatic updates insisted on poping up with a window to restart at wrong place at the wrong time. I went to click a user with Active Directory, and there popped up the restart message just as soon as I clicked.
I've done ok to avoid the prompt in the past, but now I'm ready to do something about. Is there a way to suppress the popup window asking to restart?
Your "servers" should be in a separate OU. This OU should have a GPO linked or inherited to it that governs the Windows Update settings for the box. Among these settings in the ADM template are ones that suppress most of these Windows.
