We have a 4402 controller managing 27 ap's. When we connect new laptops to the WLAN, we cannot join the domain but can get on the internet, so it doesn't look like a DNS issue. If we plug the laptop into a network drop, it can join the domain fine.
Also, since moving to LWAPP and implementing the controller, existing clients are having trouble pulling roaming profiles, printing to network printers, and accessing network apps on servers (some on the same subnet).
Has anybody seen problems like this?
