Windows Update "restart" dialog pestering users

If I'm posting this question in the wrong group, just let me know.

I'm running TS on a Win2003 Server. I received notice that there were
new updates available from Microsoft that needed to be installed. I
figured, "What the heck, I'll download & install them and then wait to
reboot until it is convenient."

Obviously this is a bad choice. Now, all my TS users are recieving a
dialog that says:
"Automatic Updates
Updating your computer is almost complete. You must
restart your computer for the updates to take effect.

Do you want to restart your computer now?"

They then see two "grayed-out" buttons that say, "Restart Now" and
"Restart Later". They cannot click either of the buttons nor can they
close/dismiss the dialog box. Their only option is to drag the dialog to
one corner of the screen and go on about their work.

I, at the administrator console, keep getting that dialog about every 5
minutes! I COULD click the "Restart Now" button... but I don't want to
just yet. I click the "Restart Later" button, the dialog goes away...
AND COMES BACK IN 5 MINUTES!!!

Surely there is some way to prevent my "Users" from seeing this dialog
at all. And surely there is some way to make the computer wait longer
than 5 minutes to ask me if I want to restart... again!!!

Somebody please help!
