Hi Steve,
Thanks for your additional pointers! All of the DCs (using the AD Sites
and Services GUI) all show this server in the site it was moved to. Yet, the
moved DC seems to think that it still in the old site. There are registry
entries in the registry that still identify the old site. My goal is to get
this DC to a stable condition and then DCPromo it out. Since I don't plan on
having this server in any other site, maybe the "sitename" registry would be an
OK way to go? I am still confused why things don't happen automatically in a
logical fashion. I would expect the netlogon.dns file to reflect the new site.
Yet it doesn't. This DC was the only one in the old site. Would that make a
difference? I recall at one time (for a completely different reason) deleting
the netlogon.dns (and netlogon.dnb too?) files was a solution. Would that be
a wise thing to do? Since there are no more computers in the old site, would
it make sense at this point to just delete the site or would that mess up the
situation even more?
I will check out your references tomorrow. (I am at a family function right
now and was really anxious to see if anyone had responded to my query.) Thanks
for the help!
-mike

Subject: RE: [ActiveDir] concern about re-ip'd DC
Ok I see in your original message that you state you did try to move it via
sites and services, missed that. When you did this what server was the Sites
and Services MMC focused on your DC or another DC in the domain? Did the UI
update to show the server in the correct site after the move or did it simply
remain the same? If you focus on another DC and make the change and then wait
for replication does the site get updated? Is the server that you are trying
to move healthy from a replication standpoint? The SiteName parameter was put
in the registry for troubleshooting and testing purposes and while it can be
used it can also cause confusion later if you decide to make another change as
that value always overrides.
Thanks,
-Steve

In addition just so no one thinks this recently changed the behavior was also
described in the Windows 2000 Distributed Systems Guide as well:
http://www.microsoft.com/resources/documentation/Windows/2000/server/reskit/en-us/Default.asp?url=/resources/documentation/Windows/2000/server/reskit/en-us/distrib/DistSystems.asp
"If a domain controller's IP address or the subnet-to-site associations are
changed after Active Directory is installed on the server computer, the domain
controller does not change sites automatically. It must be moved to the new
site manually if that site is the desired location."
Thanks,
-Steve

The following documentation describes this behavior as well:
http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/activedirectory/stepbystep/adsrv.mspx
"All newly promoted DCs are placed in the Site container that applies to them
at the time of installation. For example, a server bound for California might
have been initially built and configured in the Maui, Hawaii, data
center-therefore, the Configure Your Server wizard places the server in the
Maui site. After it arrives in California, the server object can be moved to
the new site using the Sites and Services snap-in."
If you do not want to use the UI a script was included in the Branch Office
Guide called movesite.vbs that will accomplish the same thing.
Thanks,
-Steve

We do not recommend changing the dynamicsitename parameter and hard coding it
using the SiteName parameter is also not recommended since later you may forget
that this is set and no matter what you do the DC will assume it is in the site
you put in the key even if that site does not really exist. As I stated below
Domain Controllers are special when they are promoted they look at the site and
subnet mappings and place themselves in the correct site. After that you must
manually move them through the Sites and Services Snapin. Simply launch the
MMC navigate to the old site and look under the servers folder, select the
server you want to move and drop him in your new site. Are you stating that
you did this and the server did not show up in the new site? There are many
reasons why DCs do not dynamically change sites most revolving around keeping a
stable replication environment.
Thanks,
-Steve

Hi Steve,
(Maybe I should add this issue to the "OT-Biggest AD Gripes" thread!) Each
of the actions I've taken so far, in my mind, should have gotten this DC back
to the appropriate site. But it still thinks it should be in the original
site! One item I find is the
HKLM\SYSTEM\CCS\Services\Netlogon\Parameters\DynamicSiteName still points to
"site2". I did run across a Microsoft article that talks about this and to
never change a dynamically determined value. Instead. you can create a a new
value in the same place in the registry named "SiteName", REG_SZ with the value
you want. Have you (or someone else) found the need to do this?

DC do not change their sites dynamically. You will need to move the DC
to its new site manually via sites and services. When they are promoted
they look at the site definitions but after that it is a manual process.

Hi,
I have a Domain Controller that was located in a different AD site
(site2) via its IP (naturally!). This DC was shut down about 2 weeks
ago. I have since powered it back up offnet, given it a new IP (which
is defined as a different site (site1)), and rebooted it on net. Some
hours later, it still seems to think it is in the original site (site2),
at least that is what I see in AD Sites and Services.
Some minutes later...based on some googled and eventide.net info, I put
in a specific subnet entry in ADSS for this new IP and associated it
with site1. A reboot produced no change. So then I went to AD Sites
and Services and did a GUI move of this DC from site2 to site1. Another
reboot - no change.
I see the dynamically created netlogon.dns file STILL has site2
identified! Any hints on how to "convince" this DC that it should be in
site1? Anybody else experience this type of behavior? TIA!
Mike Thommes
