Thanks Paul,
Your guide is great. 1 problem I encountered (which took 2hours to figure out) is that you have to specify the username as user@ and leave domain field blank in XP. Both in Windows Managed and Intel Pro wireless management software.
e.g
___________________________________
Step 1 of 2 : PEAP User
username: rockwater321@localdomain
Domain:
Password: xxxxxxxxx
Confirm Password: xxxxxxxx
__________________________________
I found that entering entering localdomain in Domain: does not work. Just a heads up for others out there
