I have RRAS set up on Win2K8 R2. Authentication is EAP MSCHAP v2. It's working fine with XP and Windows 7. However none of the Vista clients can connect. I set up Vista running in a VM here so I had a client I could test with. I disabled the firewall. It's a fresh, clean install. I have no firewall running on the parent OS (win 7 x64) and the parent can connect fine to the same VPN. I'm looking thru the Vista client logs and have found a few things of interest that I've googled, but really haven't found any sort of solution.

Requested EAP methods not available. You can see in this screenshot of the server side, I do NOT have MS-CHAP v2 checked off, only EAP. http://clip2net.com/clip/m29510/1294852696-clip-27kb.png If I check off MS-CHAP v2 in addition, the win7 and xp clients can no longer connect. This is a screenshot of a working win7 client config: http://clip2net.com/clip/m29510/1294852785-clip-26kb.png This is a screenshot of a non-working Vista client config: http://clip2net.com/clip/m29510/1294852893-clip-64kb.png If anyone has any ideas, it would be greatly appreciated. I've spent all day working on this. Trying things that I've read about in this forum like changing the registry on the client to allow weak encryption. I'm having zero luck. Thanks very much.

thanks, i ended up opening a ticket with MSFT and after 3 weeks of india working with me and telling me several times it would be escalated and hearing nothing back for days at a time, i ended up just buying two draytek routers and getting rid of the microsoft solution. i finally got a call from an escalation engineer last week and just told him to credit back the incident to our account.
