Demoting a Domain Controller with DNS / DHCP installed

Hi,

Our environment has 15 domain controllers in 1 domain, these are spread
across the country. Each DC has DNS and DHCP installed.
I am demoting a Domain controller,

Q1 - Do i need to remove DNS DHCP before demoting or not?

I have tried Demoting already (WITH dns / dhcp STILL installed )and received
the following:

The operation failed because:
Failed to configure the service NETLOGON as requested - The wait operation
time out

Is this related to DNS and/or not being removed?

Technically, there is nothing you need to do, but....
[If the above is inaccurate, I expect to be corrected :) ]

1. Are clients using this DC for DNS name resolution? If so, they will need
to be updated to use another DNS server.
2. Are DNS servers performing zone transfers from this DNS server? If so,
they will need to be altered.
3. Are clients directed to the server for DHCP services, via routers and
switches? (bootp helper) If so, again, changes are needed.

Demoting this server should not care about dns or dhcp. If the dns is AD
integrated you will lose the dns services for this server (On the client
side) so make sure you are pointing to another dns server.

I would run some diagnostics against your AD it doesn't sound like there is
much info to provide feedback on your problem.

Go to http://www.pbbergs.com/ select the downloads link and then
click on DCDiag and NetDiag link. It will help you run diagnostics against
your dc.

I'm sure it's obvious, but the URL below is broken. use http://www.pbbergs.com

Sparks,

What you might also want to try to incorporate in your 'dcpromo procedure'
is to not point that DC to itself anymore in the TCP/IP Configuration
information as far as DNS info is concerned.

But that only helps to make sure that DNS records and the like are properly
removed (so you do not have to go in manually).

Hi

To demote the DC make sure you go into users and computers on the DC you want to demote and right click the domain. Select 'Connect to Domain Controller' and select the DC you want to demote. In other words ensure the DC you want to demote is what you are connecting to when using AD users and computer.

Thanks

Dave
