I add our notebook computers in the free authorized clients list so our school district computers do not have to see the logon screen in the web browser. Non school district computers get the logon screen which authenticates to our domain controllers. What I was curious about is last week sometime, something happened and now quite a few of the computers do not automatically authenticate through the free authorizaed clients area. Is there a text file or something that keeps this information? Is there anyway I can query a list of this clients to see if they are actually there or not?
