DNS SRV record of former PDC Emulator don't disappear when the role move to another dc

Object: DNS SRV record of former PDC Emulator don't disappear when the role
move to another dc

Hi,

Indeed, I've got 3 Windows 2000 Advanced Servers DCs in a windows 2000
domain.

When I move the PDC Emulator role on another DC in this domain, SRV record
(._ldap._tcp.pdc._msdcs.mydomain.com) of the former host which hold PDC
role, don't disappear! But a new SRV record is create beside old. Then I've
got 2 PDC SRV records! When I execute a "nltest /dsgetdc:mydomain.com /pdc",
it returns the good PDC host. It might check the date of recording to know
which is the good SRV record.

However, if I move the PDCE role back on the DC, the last created SRV record
is removed from the MSDCS PDC DNS section (._tcp.pdc._msdcs.mydomain.com)!

Anybody knows this problem?

Best Regards,



Julien

Sounds like the original _pdc record was manually entered.

Delete it. And restart netlogon.

When you say "Moved" what do you mean explicitly?

The word (moved) botthers me a bit since there are
two technically specific terms with DIFFERENT
repercussions: 'transfer' (the right way), and 'seize'
(only for true emergencies -- don't use if you can
avoid it.)

Also pt (other message) suggests a good question:
Wad the original record manually entered in DNS?

Below are DNS guidelines (not specific to this problem)
but but they include how to work on the records:


DNS for AD
1) Dynamic for the zone supporting AD
2) All internal DNS clients NIC\IP properties must specify SOLELY
that internal, dynamic DNS server (set.)
3) DCs and even DNS servers are DNS clients too -- see #2
4) If you have more than one Domain, every DNS server must
be able to resolve ALL domains (either directly or indirectly)

netdiag /fix

....or maybe:

dcdiag /fix

(Win2003 can do this from Support tools):
nltest /dsregdns /serverC-ServerNameGoesHere
http://support.microsoft.com/kb/q260371/

Ensure that DNS zones/domains are fully replicated to all DNS
servers for that (internal) zone/domain.

Also useful may be running DCDiag on each DC, sending the
output to a text file, and searching for FAIL, ERROR, WARN.

Single Label domain zone names are a problem Google:
