WPA Enterprise TKP connection problem

[Guest]

Having trouble getting my Laptop to connect to WPA Enterprise with TKIP.

I have set it up exactly how it was in XP. NOT using smartcard or
certificate, and NOT defaulting to Windows login information.

I get the popup asking for my credentials, just like in XP. I fill them in
and (user, password, NO domain) and a few seconds later it is just asking for
credentials again.

I have tried this in a limited user account and in the Admin account with no
sucess.
Anyone have any ideas?

I got the same problem when i'm trying to connect to my schools wlan. And it
doesn't matter if i'm trying to connect over 802.1X, WPA or WPA2. It's always
the same. I never had problems logging in from WinXP but under Vista I get
asked for my login twice and then the whole process just stops and i get a
failuremessage.
