Windows XP - Domain not available with wireless
We have been using student XP Laptops and trolleys for years, and one of the biggest problems with them is the message '<<domain name>> not available' when a student or staff member logs on. The same message you would get on a standard domain computer if the network cable was unplugged and there was no cached profile.
To fix this we have to plug the laptop into the network with a cable then run gpupdate from a local admin account, then reboot leaving the cable connected until it displays the logon box. This is needed often.
It looks as though when using a wireless only connection, XP doesn't fully connect to the network before it displays the logon box, and over time the computer account goes stale and the laptop is unable to authenticate with the domain.
We have tried to use HKEY_LOCAL_MACHINE\Software\Microsoft\EAPOL\Parame ters\General\Global\authmode to use only computer authentication but this didn't resolve the problem.
All the messages in event log just say unable to contact domain controller or similar network not available messages.
Does anyone else have this problem? or has managed to overcome it?
