USB Network Cards and Logon Issues

Archived from groups: microsoft.public.windows.networking.wireless (More info?)

I've got an almost Identical setup to Rick; I'm running quite a few Delll SX
280s with Dell USB wireless LAN cards. The problem I have is that the USB
cards don't seem to kick in unlesss someone is logged into the machine; This
means that a new user trying to access to the network from these machines
generally get a domain not found message. However if I login locally, I can
then access the network. In the interim, I'm having to take the machines to a
fixed point, login as the users and add a script to the startup process
Any ideas?
