I am having problems with Dell PCs and Laptops that require a user to logon twice when authenticating with the wireless network. We are running 350 APs, LEAP authentication, dynamic WEP, ACS server. Clients are running ACU 6.0.1, and it doesn't matter what client version that we use, we get the same results. The problem is when a user logs on they are asked for the LEAP authentication, and then another logon prompt appears for the Windows Network login. I have the client setup in the ACU to use the WIndows logon for authentication to LEAP. Some users do not have this problem, and some do. There is no consistency to the situation. I was wondering if anyone else has seen this problem? Thanks.
