how do i predefine wlan settings for unattended setup?

[an3k]

I would like to install windows xp sp3 unattended with domain join (active directory) on a notebook without lan connection.

Currently i have to log in as Administrator after setup finished only to establish the wlan connection and joining the domain. after a reboot i log in as the domain admin and have to remove the local Administrator profile.

How do i predefine the wlan settings i need for a connection (SSID, keyphrase, encryption mode, etc.)?
