Can someone tell me if it would be wise to put domain controllers, DNS servers and DHCP servers behind a load balancer?
I know for clients and servers and other systems that use the DC locator process that does not really make a difference but i wanted to offer HA for those systems and applications where you have to type in one or more domain controller or DNS server or DHCP server.
Also to help when we replace domain controllers. if things are pointed to ADLB.yourdomain.local instead of AD1.yourdomain.local and AD2.yourdomain.local. when times comes and you need to upgrade those 2 AD domain controllers you can include AD3.yourdomain.local and AD4.yourdomain.local and then remove the other 2 and no one will know anything different.
This came up in a discussion because we want to upgrade some 2008R2 domain controllers and some 2012R2 domain controllers to Windows Server 2016 and want to make it a painless as possible
