SQL Server requires a lot of resources (CPU and RAM) If your SQL instances take up all of the server resources, no one will be able to authenticate to your domain, DHCP can stop working, DNS lookups will fail, etc...

Besides that, Domain Controllers contain hash tables of all the passwords for every user. No one should access this box unless they are trusted, When you have something like SQL on your DC, you may need application or database support from a third party and they can access things they shouldnt
