Domain Laptop unable to browse WWW via wifi

Our laptops are all assigned two internal DNS servers via DHCP.  If a client tries to use a WIFI, the connections are fine, lookup via IP address works, but fails for dns names.

NSLOOKUP always shows the domain DNS servers, even if we add a opendns server to the dns list, it still fails to look further than the internal DNS.

Clients are all winXP Pro, SP3

Disabling the LAN port and playing with binding orders has changed nothing

There is only one DNS server showing in that output.  Are you sure there is more than one being picked up?

you IP config shows your WIFI router as your DNS server
either change DNS on router or on client

Change DNS to google DNS

http://code.google.com/speed/public-dns/

 8.8.8.8 and 8.8.4.4

or Google for free public DNS servers and change

by default, most wifi will give out just the wifi router IP as the dns server.  this is the correct way for clients to do dns lookups.

A laptop that is not part of the domain can access the internet just fine via the same wifi with the same IP configurations

open http://192.168.1.1
Login with Admin/Admin or Admin/password

Change DNS to  8.8.8.8 and 8.8.4.4

Sorry, that is not a solution, the local McD / Cloud / Costa will not allow access to their routers

So, if you use NSLOOKUP on one of the affected laptops, what happens?

it fails on the two internal dns servers, does not list any attempts at the wifi assigned dns, even if the lan port is disabled.

OK, found the issue.

in AD, the DNS servers were set, this always overides any DHCP settings.  This has been reversed and all is working :)
