Just recently I have encountered a problem with my server. I am running Exchange 2000 and have made no recent upgrades or updates. However over the past 3 weeks the server has stopped repsponding 3 different times. My solution has been to just reboot the server and it starts working fine. No messages are ever lost. If soemone send an e-mail to one of our addresses, it will just sit in our que. Also, we are able to log in, it jsut never brings up the mail. Even from web access, we are prompted for username and password, but than it never brings up the mailbox. Has anyone else experinced similar problems or have any ideas what may be casuing this. I would be more than happy to supply more information if needed. Thanks for any assitance.
