No, which is rather odd, unless I'm looking in the wrong place.  I've checked 
the System, Application, and even the NP&AS logs....  I have 4 errors in the 
NP&AS Server Role Event log, but that was what I expected from fiddling with 
the RADIUS Server setup (Invalid RADIUS client).

Do you see anything in the Event Viewer related to these authentication 
attempts on the NPS machine?

Thanks!
Tom

Thanks Tom and Jim,

Yes, Jim, it looks like that.  Odd thing is, that I can tell the RADIUS works 
fine (the client/server piece).  However, the 691 error, I think, is the actual 
authentication against AD because I keep getting the error that the credentials 
are invalid on the domain.  When I disable pieces on the NPS, like the actual 
RADIUS server, there is no communication between ISA and W2k8 - I get errors I 
expect.  I've done a lot of Googling last night, and many others have the 
RADIUS working, but in my scenario, the credentials just don't seem to be 
authenticating against the AD.

I've checked the logs, even the event viewer, and when I disable the RADIUS 
Server, again, I see errors I expect, but when all is configured, I don't see 
anything in the logs about the rejection of the credentials.  I'm sure it's 
something very simple that is done differently in NPS, probably additional 
checking, but I've tried to mimic the 2003 policies to a T and can't get in.

Gecher RADIUS logs.
They're in the same place they were on WS03.
Does your RADIUS configuration look like this?

Subject: [isalist] VPN Authentication w/Radius to Server 2008

Our ISA 2006 box is not on the domain, so we use RADIUS to authenticate VPN 
users against the Domain.  We've been successfully using RADIUS on a Win2003 
Server without issue for quite some time now, but I'm now transitioning to 
Server 2008 and am having a bear of a time with Authenticating users via VPN.  
All seems to be fine on the actual RADIUS server/client communication, but it 
appears that NPS on Server 2008 (the IAS replacement) keeps giving me the 691 
Error (bad username/password) when I try to VPN.  It appears that NPS on Server 
2008 can't authenticate users against the Active Directory.

I know this isn't really an ISA issue, but if anyone has any help or documents 
they can point me to, that would be excellent.  I've done the MS one on adding 
the domain\ before the username, but that didn't solve the issue.  Anyone have 
NPS configuration issues with VPN and experience with solving them?

Thanks.
