Can't find Domain controller on wireless subnet

We just aquired a few laptops. I've configured our Linksys wireless access
point as a separate subnet (192.168.0.x) and connected it to our LAN as
90.0.0.9. My domain controller is at 90.0.0.2. I can access the internet
from a wireless laptop (its running Windows/XP Pro SP 2). I can ping the DC
using its IP address, pinging a public web site also works. My problem
shows up in that I can't get the laptop to join our domain. When I change
its name and attempt to join the domain, the domain controller can't be
found. I'm stuck and any suggestions would be greatly appreciated.

Thanks,
Bud

Possible:

If you are using the Linksys' DHCP function to configure wireless clients,
try manually configuring them instead. On many low end routers if you use
the DHCP function to configure clients with an IP of 90.0.0.2 for DNS, they
would actually get 192.168.0.1. Queries go to the router and then the
router forwards them to 90.0.0.2. Generally this works OK, but one of the
times it is most prone to failure is the domain join process.

I am having the router assign IP addresses. The first laptop got
192.168.0.2. Are you suggesting that I turn off the DHCP function and then
manually assign the laptop 192.168.0.2?

Thanks,
Bud

Yes, manually configure all TCP/IP settings:

IP = 192.168.0.2
Subnet Mask = 255.255.255.0
Default gateway = 192.168.0.1 (router's IP)
Primary DNS = 90.0.0.2

If doing this enables you to join the domain, you may be able to switch back
to DHCP thereafter.

Oops, forgot - you do not have to turn off the DHCP function to use static
IPs. Just make sure you don't wind up with duplicate IPs.
