Where's the WARNINGS and flashing red lights about this ? Had someone
troubleshooting a problem on a DC notice that the dhcp client service
was running and thought he read somewhere that it could be a problem.
He then proceded to manually stop the service on multiple DC's and
Exchange servers.


When he did so, the DNS records disappeared for these boxes and the
entire network was basically down. What is the caveat with this ? Does
stopping the DHCP client service actually UNREGISTER DNS records ?
What am I missing ? Even called Microsoft and they couldn't even tell
us for sure that stopping that service on DC's would have this drastic
of an effect. Starting the DHCP service on all of the boxes got us
back up again but......


......I want the LONG VERSION of this story please....


Thanks much.

There's no long version, just the short. This service is an ABSOLUTE
requirement whether the machine is a DHCP client or has a static IP. It's
THE resolver service and provides DNS dynamic registeration. Period.

the netlogon service registers SRV RRs

I assume you are talking about the A and PTR records of DCs?

Jorge, actually that's correct about the Netlogon service performing the
registration, but the poster was referring to why stopping the DHCP Client
Service disabled registration, and that's because the Netlogon service,
along with simple registration and hostname resolution absolutley relies on
the DHCP Client service started in order to work.

I hope that helps.

Cheers!
