We were runnig fine until I installed sp1 on my CAS servers. Outlook was no
longer able to connect to our casarry.company.com address.
casarry.company.com points to a CISCO CSM hardware load balancer which then
points to both of our HUB/CAS servers. Once we installed sp1 Outlook
clients would not longer open saying it could not connect to the server.

However, if we added an entry in our host file that pointed
casarry.company.com to the IP of one of the Mailbox servers then all was
well with the world.

Anyone know what changed? Did sp1 add or change some ports? Do you have
any websites that talks about it?

Thanks for any help!
