I have some new Dell 5420s with the Intel Advanced-N 6205 that are running Win7 Pro, 64-bit. The issue I am having is using domain accounts to login to my wireless network. When trying to login, I cannot get a domain user to login via wireless. The message I get is, "There are currently no logon servers available to service the logon request." If I attach a network cable tp the laptop, any domain account can login to the laptop. If I login to the laptop with a local computer user, I can see that the wireless profile does load for my wireless network. I have also changed the power options for the wireless adapter to maximum performance.
I have updated the driver for the wireless card(Intel download) and BIOS of the laptop. No luck.
