Windows 7 Pro Cisco AP, PEAP, MS Windows2003 IAS -

[standard9755]

LinkBack Thread Equipment Exhibit Modes We now have configured a wireless network employing PEAP (WPA & TKIP),Windows 7 X86, Cisco
1200 AP,Windows 7 Pro, and Windows2003 IAS. 90% of the time this is working
perfectly however,Microsoft Office Professional 2010, users are getting kicked off the wireless network
and being forced to re-authenticate. The only indication of a problem
is the IAS server logs a authentication failure.
First you see
User xxx was granted access.
Fully-Qualified-User-Name = FQDN PATH
NAS-IP-Address = 10.x.x.x
NAS-Identifier = OURAP
Client-Friendly-Name = OURAP
Client-IP-Address = 10.x.x.x
Calling-Station-Identifier = Client MAC Address
NAS-Port-Type = Wireless - IEEE 802.11
NAS-Port = 1983
Proxy-Policy-Name = Use Windows authentication for all users
Authentication-Provider = Windows
Authentication-Server =
Policy-Name = Wireless Authentication
Authentication-Type = PEAP

And the user is connected to the wireless network,Windows 7 Home Basic Key, a little while
later
