we recently had a number of issues on our network resolved. DNS DHCP etc... on our edge (DMZ) is a UAG server where all services through this are running.
the issue is that our Direct access service on this is dead. Server 2008R2 and UAG 2010
None of our clients can connect to this service anymore.
we deauth'd a DHCP and running only one now. two DC's server 2008R2
The engineer moved the DNS server, did the whole scavenger thing, and then rebuilt it.
not sure if that might have broken anything. But since then everything has died. we did also upgrade the NLS cert which sits on the CA server. the DA verification gave the green light on this one.
any guidance is welcomed!
oh... should the DC's with the DNS have ipv6 enabled? or just the UAG?
