Computers Leaving the domain..?



We have a 2k3 small business server acting as our PDC.

We have recently deployed a number of new Motion tablet PCs to our
organization running Windows XP Pro Tablet Edition, bound to our only domain.

Suddenly (2 weeks since deployment), we are noticing that the machines for
some reason are dropping from the domain. Opening up Active Directory Users
and Computers will reveal that the machine account is gone! I have not quite
figured out how to reproduce this yet...

Syptoms: At the windows login, tablets I (or other users) have logged before
will report that the domain is not avialable... At this point I have no
remedy but to log into the local administrator account. Users can't even log
in as themselves and access their cached accounts. Once in as administrator,
I can join the tablet to a workgroup, then rejoin to the domain and be
fine.... I haven't confirmed this has happened to tablets that have already
been rejoined, however, I'm pretty sure I've had to rejoin a couple twice.

Any ideas much appreciated!!



Hi Sean,

Yiou may want to try enabling auditing for the domain to see what was
deleteing the computer objects, also look for any products that sync object
data with your AD as these could get confused and over write objects with
nothing, effectivly deleting them.
