Login to NT Domain Through Wireless Apple Airport

[mmaki]

I have started a wireless network with an Apple Airport base station. I can access all resources from WIN 98/2K portables but only by manually mapping and I can get to the Internet. I can not get the portables to find a domain server for validation or running login scripts. I have the Airport doing DHCP for 10.1.1.X network for all the wireless clients. I have statically entered my WINS server on the portables. All looks good when I run WINIPCFG/IPCONFIG. Everything seems to be in place. Any ideas?
