Wireless Laptops - Domain not available
We seems to be getting a lot of problems with our wireless laptops (and a few wireless desktops).
They will work fine for serveral weeks and then suddenly someone will try and log on and get the error message: "Unable to log on, the domain is not available".
Logging on locally it is clear that the wireless network is still connected with a good signal. The machine is still in active directory and still has a valid IP address. The only fix is to rejoin the machine to the domain, and then it works fine again.
This only seems to affect wireless clients and seems to be very random. We have a Meru wireless network. Does anyone have any ideas? I had a previous suggestion that this might be caused by machines that had not been sysprepped, but all ours have.
