We have a network that spans multiple physical locations. Each physical location has it's own server running DHCP. It's configured to be a single domain via routers (nothing fancy). The domain controllers (primary & backup) are located at the home office. So my question is about best practices with DHCP configurations. These remote servers currently give out two IPs for DNS resolution:
1 - their self
2 - the primary domain controller at home office
They don't reference the backup domain controller. Is this the best strategy for configuring remote DHCP servers? If not, how should it be configured?
