I configured dot1x on a 3550 port which is connected to a Windows XP client. I am using radius and I can do debug authentication and I see the switch asking the client to authenticate, however the client machine never prompts for authentication. The state goes automatically to unauthorized. I have configured the client for MD5 authentication. Is there a trick to getting the client to prompt for credentials? The docs that I have read show a balloon pop-up on the client that says to click it to enter credentials but I never get this balloon. I have tried this with 2 separate clients with the same results...
