Server 2008 Registered DNS entries intermittently vanishing from DNS

-

we have ~ 40 servers static ip addresses ‘register in dns’.

 

we dcprpmoed new dc (2008r2) , have servers looking new dc dns primary , 1 of older dcs secondary dns lookup.

 

all 3 dcs replicating dns ok (checked via command line) , after ~ 18 hrs after pointing servers @ new dc primary dns, dynamic registrations getting lost / new dc wont return registrations when queried dns clients.

 

the quick fix has been hop server registrations have vanished (or new dc has decided not spit requesting dns client) , run ipconfig /register dns.

 

i have seen severs ‘disappear’ within ~20 min of /registerdns.

sounds duplicate zone issue. i've seen before.

when or whomever promoted new server, did manually install dns, , manually create current ad zone, or allow replicate automatically (such go lunch , come , find zones populated in console)?

if or else manually created current ad zone, possibly thinking quicken replication process, you've introduced duplicate zone.

to understand is, how may have occured, , how fix it, please read blog on subject:
