Hello - we have a network of Outlook 2010 users logging on through Exchange 2003 Server (2003 Server platform) who for the last 2 days have experienced "freezups" and loss of connectivity. We have had to reboot Exchange in order to fix it. It's happened twice in 2 days now. We're seeing some new errors in EVENTVWR on the server, and are looking for help in troubleshooting what is going on. I am attaching some of the errors below. Thanks for your help!
