Moving DHCP

let me start saying, have 1 dhcp server. on servera 2008 r2 physical dc.

i putting plans moving our dhcp servera vm named serverb.

serverb 2008 r2 server not dc. 

the question have, kind of permissions need setup ensuring new server can assume role of dhcp server? getting lost in documentation dnsupdateproxy security group in ad.

do need to:

a. create service account, add dnsupdateproxy group, add credentials in dhcp under "dns dynamic update credentials" on new server [serverb].

b. add new dhcp server [serverb] dnsupdateproxy group.

c. both & b

here our current dhcp dns settings on servera, might provide more background info:

hi,

a not required if not running secure dynamic dns update.

b required when migrating dhcp. enables new dhcp modify dns records owned old dhcp server.

for information:

dhcp: credentials dns update should configured if secure dynamic dns update enabled , domain controller on same host dhcp server
