Ather,

Normally this type of problem is a result of DNS errors. I know that you
said DNS was okay, but you did not go into detail. Please check the
following:

1. Make sure that the child domain controllers point to themselves for DNS
and not to the parent root.
2. Make sure that your child DNS server either forwards to the parent or
has a secondary zone for the parent domain name. If you are already
forwarding to the parent, you may want to create a secondary zone anyway.
3. Make sure that the parent delegates the zone for the child domain to the
child DC or make sure that the parent has a secondary zone for the child.

If you are already using secondary zones, sometimes the secondary zones get
corrupted and do not update properly. You can always delete the existing
secondary zones are create new ones.

Finally, if you are on SP4, you can run "dcpromo /forceremoval" to
forcefully demote the child domain controller. The only problem with that
is that you must then go and do metadata cleanup on the parent domain to
remove the child out of active directory. See Q216498 for instructions on
how to do this.
