Hi,
Recently I started getting complaints that internal wireless users couldn't connect to our internal network. We have the following setup:
Windows 2008 Server with NPS role installed - fully patched with the most current patches from MS.
NetGear WNDAP350 Access Point
The WNDAP350 AP is configured to use Radius and points to Windows 2008 server with NPS installed.
This has all been working fine for several years but starting about two weeks ago I noticed that users were no longer able to connect using this AP. I looked at the NPS logs and I see the following event in the event log now:
Network Policy Server denied access to a user.
Contact the Network Policy Server administrator for more information.

I haven't made any changes in the configuration other than applying the most recent set of MS patches that were released on the most recent patch Tuesday. I thought maybe the problem was the AP so I replaced it with a backup and I still have the same problem. Did the most recent MS patches break something?
Thanks in advance,
Nick
