this is a problem that bothers me for some time, each time I think I solved i comes back again. I have about 12 laptops, they all go to same wireless router, which has radius authentication with active directory to well, authenticate employees in my company. Radius and active directory are running on Windows server 2003 R2 Os. Sometimes all laptops are connected regulary and everything works fine, but sometimes 4-5 laptops can't connect not by a chance. I tryed reinstalling drivers, it didn't work, all laptops are of the same model, most of the running Windows 7 x64 and two are running Windows 7 x86.
I suspect there are problem somewhere in user/computer authentication with radius and active directory, sometimes when I restart or AD server or radius connection temporary returns to those laptops that weren't able to connect.
So can you help, is there a problem with some services in radius or AD that aren't synchronised or is it something else , and what services I need to reset on AD and radius servers so they can authenticate users normally because of what I mentioned that when I reset servers laptops gain connection?
Here below is part of log file, with user that mostly has connection problems.
