Problems with domain logon

I have a problem with wireless logon on our Win2k3 server

No matter what I do it seems that WinXP doesn't establish its
connection until after the first logon and because of that it doesn't
apply group policies and logon scripts. After logon, when the
connection is established, you can logoff and on again and this time
the logon script works as expected - not very elegant...

After various Usenet searches I have tried the following:

1) Different policy settings a. o. Always wait for network
2) DisableDHCPMediaSense=1
3) Fixed IP/DHCP
4) SP1/SP2

Am I missing something obvious? BTW everything works as it should with
the cabled NIC.

Best wishes
