Odd DNS behavior.  Cant access with IP in IE, but can when added to hosts as a url.

I have an odd behavior with DNS I am trying to resolve.  We have a network that all log into with one common domain and use the local DNS for another domain.  When we try and find a server on the local domain in Internet explorer or other programs it cannot find it by IP.  Our workaround is to add the server name ( short name or FQDN is fine) to our hosts file on windows at the client then we can use the url to reach it. We still cant use the IP or it is an unknown entity.  The DNS is set in the DHCP call and is there, as well as records in the DNS server and a listing of the domain in the advanced tab for the DNS.  I know this sounds messy but it has been like this for a while.  I would expect this behavior if we were VPN'd in as it could not reach the DNS, but not as a local entity.  The reason we started noticing odd behavior is when we go to ssh into a box via IP from a remote VPN'ed client, we can log right in less than a second, if we log in from the local clients to a box on the local network it is 30 to 45 seconds of waiting to go to the same address.  It gets lost for a while then comes back.

Is the subnet of the local clients the same subnet as for the "box on the local network"?  Or, is it different?

It is on a different subnet than the box, it is on a desktop subnet and is allowed through to the lan subnet at the firewalls.
So, it sounds like there's a routing problem between the subnets that somehow doesn't affect local name service.  That's a pretty broad statement but may help focus on the problem.

Yet, the routing is working except it's very slow.  What does a traceroute to an IP address show?  Similar long times?  How long?  Does it maybe show you where the long times happen?

The tracert goes direct from desktop to server in <1ms so that part looks good.  Oh jeeeeeeber, there is an incorrect authentication on the ssh.  Ok that's fixed.  Now reviewing how the webpages log in going to test some more.  Familiarity breeds blindness somedays.
