Cannot connect to the domain

[Guest]

In these few months, 3 out of our 60 users sometimes have problem when login
into the domain. 2 to 3 times per week.
The message is like "Windows cannot connect to the domain, either because
the domain controller is down or otherwise unavailable or because your
computer account was not found... "
I've to remove the computer from the domain and re-jonin each time to make
it possible to login to the domain.
All 60 users have the same configuration, Win XP pro login to a NT 4 Domain.
We are also testing the Active Directory on the same network but no computer
migrated to the AD domain yet.

Could anybody pls help?

Well, your AD testing ought to be done on an isolated / lab network - that
could be part of your problem. Even if it isn't, I suggest you remedy this.

What's running DHCP (presuming you are using it), and have you checked the
workstation's TCP/IP properties when the user can't log in? What do you see
in the workstation event logs?
