DC records disappearing from the DNS

Hello,

We have a mix of 3 Windows 2000 DCs and 2 Windows 2003 DCs. Each W2K DC is
located at it's own site and the two W2K3 DCs are on a fourth site. One of
the Win 2000DC has the five FSMO roles and another Windows 2000 DC is the
only DNS that has scanenging enabled for stale records. The scavenging cycle
is 6 hours.

The problem is the property called 'delete this record when it becomes
stale' gets checked every 2-3 days for the Windows 2003 DCs and the next
scavenging cycle deletes these DNS entries, both A and PTR records. We start
having replication errors since the other DCs can't locate the 2 missing
ones.

Do you have an idea about this problem?

I would leave it at the default 7 days. 2-3 days is way too short.
Otherwise, this may not be scavenging related. If you disable scavenging, do
the replication errors disappear?
