We have 1 mac on the network that is unable to get to OWA from inside the network, when it leaves the LAN it is able to reach OWA and the mx entry to get email in entourage.
This mac seems unable to resolve any internal DNS entries via ping, safari, or most programs, though when using MS RDP client it does seem to resolve the hosts. It has no problems making it to external hosts (like google)
I've restarted services on the server and of course the mac. Because it will not see the internal addresses I am unable to rejoin it to the active directory.
Other machines, and other macs are having no problems connecting.
