SOA 'primary server' field

Setup = Win2K forest, 2 DCs [say A and B] on root of domain and 2 DCs
[say C and D] on a child of that root domain. DC 'A' is the domain
naming operations master, AD throughout, no obvious replication
problems. Symptons are differing SOA serial numbers, i.e. not all DCs
are showing the most recent version [from DC 'A' where edited] of the
zone record.
Question, should the SOA 'primary server' show the FQDN of the local DC
or should/can it be DC 'A' for an AD hosted domain? I note that if I
create a secondary zone e.g. on a child DC with 'A' as the record
master, the transferred zone shows the local DC's FQDN in the primary
server field.

Why? In a nutshell, it's per design.

In a scenario with an AD integrated zone, and tehre are multiple DCs hosting
the zone, the SOA will be in a constant flux. Since *one* of the many
features/benefits of AD integrated zones is it's multimaster feature, then
whenever a record gets added/changed/deleted on any one specific DC, that
specific DC is the SOA for that moment in time. Keep in mind there are
constant changes going on, such as record registrations from workstations,
servers and DCs as well.

Newsgroups. It is FREE and requires NO ISP's Usenet account. OEx allows you
to easily find, track threads, cross-post, sort by date, poster's name,
watched threads or subject.

Thanks Ace, they were OK so I'll look at the zone permissions and double
check the replications.

Good to hear. btw- Be careful messing with permissions.
