UAT = User Acceptance Testing?

Not sure what you mean by "working on the Laptop", but if the issue is certificate related, then it's a matter ot trust. Since you don't mention user certs, then I'm guessing you're talking about PEAP authentication. If PEAP auth works on a laptop, and doesn't work on some other machines, then the other machines don't trust the ACS certificate. The entire chain of the certificate must be trusted by the computer trying to connect. Therefore, it must trust the root (the main CA), the intermediate (if there is one), and the actual cert for the machine. If one of the production computers is running a flavor of Windows, do a Start-> Run -> certmgr.msc, and make sure the root CA is in the "Trusted" folders, make sure the issuing CA is in the "Intermediate" folder. That should do it.

If you want to really check if it's a cert issue, just disable the server certificate check on the wireless client (but I don't recommend leaving it that way).

Also - did you install the CA cert on the ACS server?

Thanks for the points - did installing the CA cert on the ACS server solve the problem?
