Do users appear correctly in DHCP and in your Certified users list? I had that error on a single user and nothing on the scale you're speaking of but I noticed a mismatch in those areas.

We are running 4.1.2.1 <http://4.1.2.1><http://4.1.2.1> successfully for the past couple months; we have two managers in redundant mode, and 6 CAS boxes. On my test machine, I can connect to the wireless network and get an IP address fine, but the Agent does not popup and when I put my pointer over the CCA agent icon in the system tray, I see the "OS Mismatch Detected" error. This same laptop has had no changes of any kind, has worked fine since we turned CCA on, and there have not been any CCA changes of any kind. I stopped and restarted the Agent, but it didn't help. I completely uninstalled and reinstalled the Agent, but that didn't work either. When I take that laptop to another area of campus, fed by the same CAS box (only a different vlan), it works fine. If I take my laptop back to the trouble area, it will suddenly work fine; a day later, if I go back there, it will stop working and show me the OS mismatch error, so it all appears to be intermittent, with seemingly no pattern. I would estimate that 25% of our users in our Library are unable to use wireless due to this problem. We are not doing any posture assessment/repair on our CCA network; it is log in via Agent only, at this time. I have a case open with Cisco, but thought I'd see if anyone has seen this before. Many thanks!
