I could go on and on… point being the more software/services you install on your domain controller the more it can affect performance and lead to disruption in services. Maybe you install an IPAM to keep tracking of available IP addresses and it takes up CPU and memory… again taking away resources from the domain services. Uh oh… Now the CPU usage skyrockets and the domain services are slow, users can’t log in and DNS requests are painfully slow. Say you just learned about a new DHCP option such as conflict detection and you turn it on for all scopes. Generally, I’ve seen DHCP servers run very efficiently and not require a lot of system resources such as CPU or memory. Installing DHCP on its own member server will reduce the attack surface of your DC. Yes, this can be corrected but why add this risk. Now your DHCP server is running with privileges it doesn’t need to perform a task which it was designed for. This violates the principle of least privilege.

Do you have guest wifi? How do you feel about these unmanaged devices being connected to your DHCP/DC server? I’m not a fan of using an internal DHCP server to provide IP addresses for the public.If DHCP is installed on the DC and a new vulnerability was discovered in the DHCP service your DC server is now at risk. The more software/services you install the bigger your attack survivance.If DHCP was installed on its own server you could reboot the DCHP server with no worries of effecting the services on the Domain Controller. If you have multiple domain controllers and it’s properly configured then these issues can be avoided but why risk it? Your users will not be able to access anything if DNS is down. This can affect authentication, replication, group policy, and DNS.

Rebooting a server with Active Directory Domain Services role on it could cause major disruption to your organization.

This can often lead to instability and disruption of services.įor example, say you are having issues with DHCP or installed a security patch that requires a reboot. Manage DC with multiple rolesĭomain Controllers with multiple roles installed are difficult to manage. Installing additional services on your DC increases the attack surface, makes it difficult to manage and can lead to performance issues. It is recommended to avoid this if you can.

It is common for small organizations to install additional roles and 3rd party software on their domain controllers. Your domain controller should be a domain controller/DNS and that is it. The general recommendation is to not run any additional roles on your domain controller other than DNS. Use IP conflict detection only when it is needed.Subnetting and benefits of network segmentation.Avoid static IP assignments and use DHCP reservations.Don’t put DHCP on Your Domain Controller.
