'Disconnected'

[Alan]

Hi,
I have a user that all of a sudden midday today his outlook 2007 went
'Disconnected'.
restarting the computer doesn't work. when outlook is reopened, is says
"trying to connect" for about 2-3 seconds then goes to 'Disconnected'.
he is able to ping the mail server's internal address without a problem.
setting up RPCoverHTTP as a patch also didn't connect.

Tried setting up a new profile, the mail server's FQDN is resolved
automatically when i put in the netbios name, and the user's full name is
resolved, but when i try to open the mailbox with the new profile, i get the
error: "cannot open your default e-mail folders........"
he can open OWA
all this, and from my computer 5 feet away, i can open his mailbox fine.

outlook log says:
