If I put my laptop in standby before I leave work and then boot it up at home, as soon as I flip the wireless switch Windows Explorer (aka Taskbar) locks up for maybe 10 minutes. I fired up wireshark once before turning on the radio and witnessed Windows trying to contact every DFS mount point in the list - which in my case is around 100. I have to believe there is some configuration option that would prevent this behavior, but I have not dug into it and even if I did find the answer it would be ignored by our client configuration team. So what I do is wait for it to lock up, then switch off the radio. This seems to abort the process and frees everything back up. When I again turn on the radio it doesn't seem to start back up.
Note that this only occurs if I were first connected to DFS shares, put it in standby, and then bring it out of standby while not connected to the Windows domain. Also note that it doesn't seem to help if I undock at work (disconnect from network) before I put it in standby.
Oh by the way... this lockup sometimes occurs randomly - it just happened as I was typing this. Same solution: shut off the radio and within 10 seconds it starts responding again.
