DHCP and DNS Question.

-

morning!

i have dhcp server set register the dns record when client gets lease.  dns registration disabled on client dhcp work.  when client first dhcp lease, dns record created on dns.  problem running when same client dhcp lease on different subnet handled same dhcp server, fails update dns.  example when client goes wireless wired connect each on different subnet.

i assume trying update created record , failing due security.  use service account dynamic dns updates , member of dnsupdateproxy ad group.

any ideas begin troubleshooting?

hi shawn,

firstly, please tell edition of os?

as dhcp clients in different subnets, recommend create scopes in  the  dhcp server , add router dhcp relay agent relay dhcp messages between dhcp clients , dhcp servers on different subnets.

in addition, using secure dynamic update dns servers might cause stale resource records. dhcp server created name can update dns records name. if client received ip different subnet, dns records cannot updated. may need add dhcp servers dnsupdateproxy group.

in addition, if dhcp server , dns server in same subnet, please make sure dns server can interact dynamically when dhcp client configurations change.

more information, please refer links below:
