Windows 7 Pro laptops losing trust relationship to domain

I have 4 laptops running Windows 7 inside this domain. Two of the laptops are having a problem logging in every morning. When these two users try to log in they get an error messege stating that "This workstation has lost the trust relationship between the machine and the domain." When I have the users walk with the laptops to a certian part of the office to log into the domain they can get in and start working normally. These laptops are all on wireless, when they sit back down with the laptop at they're desks, they have no problems getting out to the wireless. How can I stop them from losing this trust relationship between the workstation and the domain? What is causing this problem?

When I log out of the domain so I can log in locally to the machine it gives me the error that this account has been disabled. Now I cannot log back onto the domain because of the trust relationship error from previous. What should my next steps be?
If the Kimmyel's suggestion work only "temporary" and you still run into this error, you may try the Microsoft's Hotfix: http://support.microsoft.com/?id=976494 that might help you also.
TechGuy_007, when you log on "locally" you have to do it with a "local administrative account" (if there is any) otherwise you can't do anything (neither rejoin the domain)
the secure channel should be corrupted and the authentication then fails, you will need to rebuild it, here are two solutions:

1) disjoin domain and rejoin
2) use netdom command to reset machine account password, check this article: http://support.microsoft.com/kb/260575

hope it helps
