Computer Keeps un-joining domain

[John]

Is this a Windows or a network issue? Is there a solution
to this?

Thanks,

That (i.e., "unjoining the domain") doesn't really happen but a machine that
is losing it's authorization typically has a NAME RESOLUTION, usually
DNS problem.

DNS must be DYNAMIC and all internal machines must be configure to
ONLY use that internal, dynamic DNS server (set). This includes DCs
and DNS servers themselves.

Do NOT add an external server in the NIC configuration of any internal
machine.

This only happens to this particular PC. The rest of the
PCs in that building is working fine. Is it still DNS
you think?

It's the first thing I check. Also check your replication (and such
problems are usually a DNS problem too. <grin>)
