Many of our windows 7 clients have this problem. We found a solution: in the "Network Properties", go to the "Security" tab, there is a button named "Advanced settings". Play with the check box of "Specify authentication mode": some clients should check it, and others should uncheck it.
Good luck!

Specifically the client associates and authenticates properly, is assigned an IP. Shortly afterwords client is repeatedly prompted to enter their credentials. Disabling the client wlan interface seems to mitigate this for some time, but symptoms return, and interrupt client while connected to wireless network. Running Cisco Lite weight ap's on WISM's, and stand alone controllers etc. Running 7.0.98.0 code. Not seeing issues with XP or Vista machines. Only common denominator so far has been 64 bit Windows 7 OS. Doesn't seem to matter if it's Enterprise or Home version. Thanks in advanced.
