Wireless laptops lose their domain accounts

We have several mobile labs that connect to our network through wireless
access points. From time to time we have to rejoin one of the laptops to the
domain because it somehow loses it's association to its domain account. The
account is still there and active, but the PC acts as though the domain
account has been disabled or deleted.

Does anyone know why this is happening and how I can fix it?

More info needed - for example,

Is this the same laptop all the time?
Event logs?
OS version & SP level?
Everything up to date on patches?
Time syncing properly?
Are you using Windows to manage your wireless?
o you have "always wait for network on computer startup & logon" enabled via
group policy"
