Wireless Win98 pc logging into a Domain

I have a wirred 2003 Domain with a 2003 server and 18 win98 pcs and a netgear wireless access point with 4 win98 pcs and a netgear wireless access point with 2 win98 in vans logging into the domain
The Error message Domain not available comes up when logging a Wireless Win98 pc into the Domain.
Thus the login scripts on the server dont run ie drive mapping to the server fails to happen ....Is there a way i can stop the logon to server process until the netgear wireless login process has finnished.
