I have a Windows 2000 domain. Two domain controllers both running DNS and
syncing up fine. No issues with any remote 2000 or XP clients trying to
access any resources on the network.

I have setup and gotten a Motorola Q to VPN and Active Sync off of the
Exchange server. Got it to work with every web server and web enabled
device on the network. Got it to run VNC fine on every computer computer
that I tried to contact.

Everything works great except for one computer that seems to not respond to
anything that this Motorola Q asks. If I try to connect to the web server
on this one computer, the VPN will drop and then I get an error saying the
server cannot be reached. If I try to fire up a VNC connection I am told
that VNC could not connect to the server. If I try any of these things from
any desktop (don't have another smart phone available) all the services work
fine. It is just this one computer and my smartphone.

I have even tried to reference the computer by IP with no luck. I have even
thought that there might be some name confusion so I put in another DNS
record with what I know is a probably a unique name and still cannot
connect.

The only thing that is kind of unique about this computer is that it was the
first domain controller ever put on the network. When I ping my Pre-Win2k
domain name "mydomain" from a PC in the network it returns this IP address
and if I ping mydomain.com it also returns this IP.

Any ideas?
