domain profile expires

Our laptops are setup with a wireless certificate using WPA and TKIP. The
laptop does an autologon that is created while connected to the wired
network. Occassionally after a reboot the device will not autologon and there
is an error that the domain could not be contacted. At that point we have to
connect to the wired network, logon, reboot and it will autologon again.
Does a local cached domain user profile expire? Can the expiration be
disabled?
