Unable to logon as domain is unavailable

We have a set of teachers laptops, that we have reinstalled Windows XP Pro
Sp3 on, and joined the laptops to the domain, and moved the laptops into the
correct OU.

But when staff take thier laptops home, they can nolonger logon to thier
accounts, because the domain is unavailable.

They used to be able to, and i am no aware of any changes to the Group
Policies that would stop them.

I am really stuck on this, can anyone help?

Thank you.

Run rsop.msc and check for errors - also look in the event logs. By default,
anyone who has logged into the laptop once while on the domain should be
able to use cached credentials when away from that network, so if this isn't
working, something is amiss.
