Wireless IAS Authenication fails for new workstations: IAS_AUTH_Failure

Good Morning,

I have been dealing with a strange issue. I have a wireless and
Established Radius network. I have deployed PEAP with MSCHAP V2 and
TKIP since May of 2006 successfully. We use IAS server and our own
certificate server. All the servers are 2003 SP1 and the Access point
are Cisco 1100 series.

All the current workstation on the wireless network work fine. Even if
I remove and reconfigure the seting for the wireless profile they will
connect no problems. I figure this eliminates just a simple password
issue.

However I have 3 new machines I need to add and they will not connect.
The only error I get from the cards is that authentication has failed.
When I view the IAS log it give me the error IAS_AUTH_Failure. I have
confirmed these workstations have received a certificate from the
server and the credendtials are correctly entered.

I would really appreciate any and questions or comments to help me
brainstorm through this issue.

Have a great day,
