do I need the DNS Client and DHCP client services running on my primary domain controller?

Hi,

I've noticed on my PDC/BDC's (same thing almost with win2k3) that both the DHCP client and DNS client service is running in addition to the DHCP Server and DNS Server services also running.

I'm not sure if this is an out of the box mistake by MS not to disable the two client services one the server gets promoted to a Domain Controller or I do actually need both of the client services to continue to run on the PDC??

Anyone shed some light on this please?

Thanks.

Hi,

I have seen issues when you disable the DHCP client service even if the server has a static IP address. I normally leave them running.

No DNS Name Resolution If DHCP Client Service Is Not Running

Dynamic DNS updates do not work if the DHCP client service stops

Disabling the DHCP client screws up the DNS client.

Intuitive, in'nt?

its mostly used as redundancy..

If the primary server goes down, then to obtain the IP address and DNS info of the secondary server, that server becomes a client essentially..
