DHCP on child domain not authorizing

[Guest]

Hi,

Corp network and AD domain - corp.com is on 172.17.16.0

We created a new subnet - qa.corp.com as 172.17.12.0
Created the new domain controller from scratch.
added a child domain of qa to the corp.com DC
added a child dns

we have everything open across the subnets except DHCP --
as we want qa to have thier own DHCP.

I'm trying to authorize the child DC's DHCP to the
corp.com DC's DHCP, but it won't see it. does that
protocol need to be open for DHCP authorization across
subnets?

Thanks,
Ross

DHCP authorization is just an object thats added to AD that lists what
server are allowed to run DHCP. Make sure that when you authorize a
server that your DC's can locate it in DNS and there is a reverse PTR
record for it as well.
