description:
system failed register host (a) resource records (rrs) network adapter
settings:

   adapter name : {42c416c5-9fb9-4c28-80b5-5efa179b1e90}
   host name : ws150

   primary domain suffix : msft.corp
   dns server list :
      172.17.201.1, 172.16.201.1
   sent update server : 172.1.1.1
   ip address(es) :
     172.17.6.150

 the reason system not register these rrs because dns server failed update request. cause of authoritative dns server required process update request has lock in place on zone, because zone transfer in progress.

 you can manually retry dns registration of network adapter , settings typing "ipconfig /registerdns" @ command prompt. if problems still persist, contact dns server or network systems administrator.

can see ipconfig /all of 2 dc/dns servers listed in above ipconfig, please?

is zone set allow updates, , if secure only, or secure , unsecure updates?

as sysvol folder accessing using msft.corp, resolved ldapipaddress in dns. record that's called "same parent." each dc registers record ip. if record altered, or ip in there doesn't belong, cause problems. if dcs multihomed, cause problems, too.

any event log errors on dcs?
