Thanks to our outstanding wireless engineer here on the Data Network Team at Purdue, the issue of Vista connecting to the PAL2.0 wireless service is solved. If you don't have any idea of what I am talking about, I suggest reading the blog entry I created a few days ago to catch up. Turns out that the RADIUS reflector just needed a single line patch to its source code in order to correct the issue. During testing, Windows Vista was able to successfully connect to a test network that was running in an almost identical configuration to the PAL2.0 network (WPA-Enterprise/PEAP-MSCHAPv2 authentication). This does not mean that your Vista machine will connect to the production PAL2.0 network. The security team will still have to certify the change, schedule the deployment through change management, and then deploy the fix which will result in a enterprise outage of PAL2.0. There is no current ETA for when this will be implemented however, there is hope.
If you want to let Purdue know just how much you want Vista to work with PAL 2.0, I suggest contacting the ITaP helpdesk via phone by calling (765) 494-4000, or in person in STEW G-65, by filling out a web form, or by sending an email to email@example.com. Its only by your feedback that Purdue can really understand how important something is to you. There is quite a bit of truth to the saying "A squeaky wheel gets the oil."
