Need more information.
Is this a new deployment, or something that has been in place for a long time?
Has it recently started happening or always happened?

You need to provide context because there are many different reasons for the authentication prompt.
It could be as simple as an SSL certificate error, to a misconfiguration elsewhere. If the problem is new, then it could be a bad patch from last week (Windows 2003 DCs only).

Not enough information.

This setup has been in place for a long time. what I did was updated the server 2003 with Microsoft updates on Sunday and I got this error on Monday. I also updated the Exchange server.

Microsoft have pulled the update and replaced it with another one.
If you run Microsoft Update you should get asked to install the updated patch. After rebooting the domain controllers the problem will be resolved.

Sorry to bother you again, for some unknown reason some users are getting the same popup dialog box on their email screen. I remove the KB3002657 from the DC and Exchange Server, but it is appearing on the clients machine again. Is there something else I need to do? Help!

Have you run Microsoft Update again to see if the updated patch is offered and then installed it?
If not, then you need to do that.

Don't forget to reboot the servers afterwards.
