Unable to access remote site - same domain

We have two offices, one in OKC, the other in Tampa. These sites are both on
the same domain with the OKC site having two DC's and Tampa having one DC. I
reside in the Tampa office and recently went to the OKC office with my
laptop. When I connected to the LAN there I could access all of the servers
in OKC without problem. But when I tried to access any of the Tampa servers
I wasn't able to. I first thought it was just a networking problem with our
frame relay but when I went to any of the OKC systems (PC's or servers) I
could access everything in Tampa. When I tried to trace route to a system in
Tampa from my laptop it would just time out -- even at the first hop.

The weekend before this started to occur we had split our network away from
a partner company that we had been sharing networks. When we shared networks
we were still on our own separate domain but we did share a WINS server. Our
PC's used DHCP to obtain their IP addresses but DNS was statically assigned.
After the split I setup a DHCP server on our network where I pushed out the
same DNS servers that were being statically assigned.

I'm guessing something with this split is causing this -- although it seems
to be a problem with the laptop itself.

Any ideas?

Can you ping the Tampa computer by IP?

No, it just times out. So it doesn't appear to be a DNS issue. It seems to
be something on the laptop itself. It's as if the laptop is somehow blocking
that access to Tampa. Even if there were a routing issue or some other
network issue -- when we do a trace route it should still show it making that
first hop to the gateway in OKC. It doesn't even do that.

Post the routing table here may help.

I should also ask IP information on both sites.

It turned out this was a problem with the VPN client software we use. It was
bound to the NIC. Once I disabled that everything worked normally.
