Folks:

I have 2 Domain Controllers on my home network. Now I want to delete Active
Directory from my second Server (that does not contain Global Catalog).
However I keep getting the following error message:

**************************************************************************
The operation failed because: The Directory Service failed to replicate off
changes made locally.
"The DSA Operation is unable to proceed because of a DNS lookup failure"
**************************************************************************

What steps do I have to take in order to remove Active Directory from my
second Domain Controller ?



Thanks,
John.

If it's a DNS lookup failure, I would make certain that all the DCs are only
using your internal DNS server (not your ISP;s or router). This should be
true of ALL internal machines that are part of AD. Use a forwarder for
efficient Internet resolution.

If this is not the problem, then I would look at DNS to ensure that the SRV
records exist (which is what it's looking for).

John,

It sounds like your 2nd DC is having communication issues with the other
DC. If you are at Service Pack 4, you can execute 'dcpromo /forceremoval.'
This will look and act like the normal DCPROMO, however it will ignore the
fact the you are unable to replicate off the changes to the other DC.
Before doing this you will want to make sure that the remaining DC has all
of the FSMO roles. From the remaining DC, install the support tools from
the Windows 2000 Server CD. Then, open a command prompt and type 'netdom
query fsmo'. This is tell you who are the FSMO role holders. If they are
all on the remaining DC, then proceed with demoting the 2nd DC. After
demoting the 2nd DC, you will need to do some housecleaning, known as a
metadata clenaup, on your remaining DC to make sure Active Directory knows
the 2nd DC is not longer a DC. Below are some articles that will help you
with all of this.
