Windows 7 slow to logon to Server SBS 2003

We have several laptops with Windows 7 Pro and only one of them is giving us this problem.  If we leave the IP address and DNS set to DHCP assigned the laptop logs onto the server normally but we get no internet. If we put the server IP address in the1st DNS field we still get no internet but logon is ok.  If we put server DNS 1st and router address for 2nd DNS we get internet and logon is fine but only for the 1st logon.  If we restart the computer and try to logon a second time it takes 4-7 minutes.

Frontier replaced defective modem/router and problem was fixed.
On the Pc set the first dns to the server and don't set a second dns. Reboot and logon (this will clear the DNS cache).

once logged on do a NSlookup to a Internet site (see below)


You should get a response like this:

Server:  UnKnown
Address: (your local server ip will appear here)

Non-authoritative answer:

If it shows the correct local server but does not show the correct public IP for website (ibm in this example) then make sure you have internet Forwarders set on the local DNS server.

were all computers joined to the SBS domain using http://connect wizard?

Please post ipconfig/all of server and that workstation.

This problem started only after Frontier communications replace the Modem/Router with a new one that has a static IP. Remember this is ONLY happening to the one laptop.  All other computers are fine. I will post ipconfig/all info tomorrow when I get back onsite.
Is the DHCP server service running on your server? Is possible the new router is doing DHCP. If so disable DHCP on the router and start DHCP service on your SBS server. Its possible this only affects this system as the others my not have renewed their IP addresses yet.
Check the forwarders in your DNS on the Server. Ensure they are correct.
Ensure DHCP options has the DNS Server Listed
