I'm installing Windows 7 Enterprise Edition 64bits in a lot of HP laptops (EliteBook 8440p) at this moment I'm writing this post. I setup remote desktop in everyone of them. Then I have to test RDP from another PC. So far I come across the same problem with all of them: When I choose to logoff RDP session, the screen just displays "logging off" forever! So I always have to cut off the connection after my patience has reached its limit. I've found another thread talking about the same problem in Vista and Win7, but I don't have Zone Alarm. And I have no idea what to look at.

Hi, Please update the BIOS and the network card drivers first. If it does not work, you may test the issue in Clean Boot to check if there are any software conflicts.

Everything is up to date already. I'm working on the clean boot.

I've found the culprit. It's a service called "Broadcom Wireless LAN tray service" (wltrysvc). I suppose Microsoft can do nothing to this problem, right? And I have to turn to Broadcom... great... Your "clean boot" suggestion is very helpful.
