Unable to connect wirelessly after windows update??

So I have a very odd thing going on.  Wireless was working fine on Friday.  This morning, some of my users cannot connect.  The wireless controller indicates an authentication failure.  So here it the odd thing I can connect with my iPad, and with my Android.   I suspect it has to do with the updates that users installed on Friday.  Any one have any ideas?

Thanks in advance for your help,
