I've been trying to get my XGS to handle DHCP for a small lab and update my internal DNS zone automatically. The documentation mentions it's possible, but I couldn't find a clear end-to-end example.

My DHCP scope is handing out addresses, but the DNS records aren't being created. Has anyone successfully set this up with an internal Windows DNS server? I'm specifically unsure about the credentials the firewall should use for the dynamic updates.
