Long pauses when accessing UNC paths

We experience long pauses when accessing Windows UNC paths on our network.  We have been a Novell Netware shop for years but are migrating and have noticed this delay.  Is there some DNS settings we should check?  We have two domain controllers with AD integrated DNS.  These DC's have been running for more than a year and service internet name resolution for our organization with no issue.  We do have WINS enabled and these servers are in our DHCP scopes but I wonder if these are even needed still.  Anyone have any tips on things we should check to ensure we eliminate any delays?  It happens when accessing our DFS name space too.

I am assuming server1= Primary DNS server and server2=Secondary DNS server in dhcp? If so have you tried switching them? Also make sure you enable all dns logging for event viewer and see if there are any errors that come up in event viewer. Also, is it EVERY unc path on the domain that causes slow responses, or just when you access shares from the servers?

Yes, the primary DNS server is also the primary DHCP server.  Remind me why that would be a problem, especially when this server is performing well and barely being hit?  I seem to recall that this can be an issue, but don't remember why.  We've tried this with multiple UNC paths with similar results.

Make sure that you have Netbios over TCP\IP enabled.

Make sure all clients and servers only point to your 2 DCs for DNS. There should be no external DNS servers listed.

Post dcdiag of a dcdiag to see if you have any errors.

It shouldn't be an issue. I meant in your dhcp settings, try changing the priority of the dns servers, or even just change the priority statically on a pc, or just put only the other dns server to test if one server is providing better lookup speeds than the other. This will help narrow down the problem.

Also, when you ping a server or pc by name is it taking a while to resolve?

Thank you for the tips...some of these i will definitely check.  However, we think we found the problem after digging some.  The delay only occurs on workstations with the Novell client installed.  On workstations without the client the response is fast and well within range of acceptable.  We believe it is due to a setting in the Novell client:
Novell Client Properties, Advanced settings, Name Resolution Timeout.. change from 10 to 1
When we made this change, it was fast even with the Novell client on a workstation.
