XP clients registering unauthorized "Same as Parent" record

[Guest]

Hello,

I've been combing the Web trying to figure this one out, but I'm stumped.
Our large multi-site network has a root domain and two child domains, with a
total of 14 domain controllers. Each separate location has a DNS server that
is configured as a slave to the primary internal DNS that runs on one of the
DCs for the root domain.

Everything works great, except that periodically we start having logon
problems and - almost invariably - the difficulty is that an XP machine has
registered itself (or been registered) with a "Same as Parent" record in DNS,
resulting in some requests for the root domain going unanswered.

I initially thought it might be an issue related to defining
workgroup/domain membership after re-imaging a machine, but just this week it
happened with a machine that's been stable for nearly a year.

I'm stumped... anyone have any insight?

This pops up occasionally, I think you will also find it is creating SRV
records. Call MSPSS for the hotfix or apply SP2.
Netlogon incorrectly registers SRV records in DNS for Windows XP-based
clients:
