[Pauldotcom] Configuring WPA2 & RADIUS

[Tim Mugherini]

Robert,

First I would not trust the Radius server logs, grab  a packet dump to
verify they are not trying to auth as the computer acct (I have seen
MS IAS not log attempts so even though I have no experience with 2k8
NPS I would not trust the logs)

Also you mentioned diff buildings, diff subnets? AD sites?

Lastly you mentioned certifcates are you using a self signed on the
Radius server, MS CA? If MS CA what are your GO settings for the
Radius and Certs (have seen issues with MS CA and "verification" on XP
so just a hunch on my part.
