Hey guys, about to pull my hair out here.

This is a new install with exchange 2007. I set up everything yesterday and had it working with various users all day and night. This morning i had to reboot my exchange. Once i did that BES no longer works. I've have tried everything. It is not seeing the mapi profile. When i try to reconnect it says "The name could not be resolved. Network problems are preventing connection to exchange..blah blahh....I can ping exchange by name just fine, it's on the same domain, permissions are set correctly (remember it WAS working)....please help..thanks.
