<div>
Have you removed the bridgehead function from the 2003 server in question, just checking as you don't state it above?
</div>


<div>
Hi DLeaver, <br />
<br />
No I haven't. I thought it was an automatic election process. How would I go about doing that?<br />
<br />
Many thanks
</div>


<div>
Same way as adding one, but in reverse<br />
<br />
If you go into sites and services &gt;&gt;&nbsp;select the server &gt;&gt;&nbsp;right click and properties - remove the IP function from the bridgehead section &gt;&gt;&nbsp;ok to exit.
</div>


<div>
2003 DC is not a manual selection. See attachment. So it does not have the option to remove IP from the Bridgehead section.<br />

<div>
That is where the manual selection would take place.<br />
<br />
If you have elected a preferred bridgehead and this server's properties shows it as removed then it shouldn't be an issue to remove it.<br />
<br />
Does your new bridgehead for that site appear in the repadmin output?...

<div>
Think that is related to Exchange not AD, where 2003 used to use bridgeheads...
</div>


<div>
This is what it looks like in 2003 box sites and services. Also, on the same box it has updated my manual selection. See attached<br />

<div>
so, on the output on repadmin /bridgeheads do you still see the 2003 server in question as the bridgehead for that site or do you see the new bridgehead server?
</div>


<div>
I still see the 2003 box. Nothing has changed
</div>


<div>
Thanks! I will give it a go next week and see how it goes.
</div>


<div>
Dcpromo worked fine on the 2003 box. Initially the new DCs were throwing an error when I ran 'repadmin /bridgeheads'<br />
<br />
Then in admin command prompt, I ran repadmin /syncall<br />
<br />
This did the trick and KCC kicked in to select a new bridgehead for the site.<br />
<br />
Thank you very much for your help.
</div>


<div>
Dleaver was right. it being a bridgehead did not stop us from demoting the DC.

<div class="content wysiwyg-content">
We have had a Windows 2003 AD server which was acting as a PDC. Since then we have introduced 2012 AD boxes and the FSMO roles have been transferred to them. Currently 2003 box is on by all the AD DNS services are off so that no one can query it as a DC. <br />
<br />
The problem I have is that when I run <u><b>repadmin /bridgeheads</b></u> command it shows the 2003 box has bridgehead for this site. <br />
<br />
I have gone into sites and services and manually selected a bridgehead for the head-office. This setting has replicated to the other sites but if I run the repadmin command again, it still shows the 2003 box. <br />
<br />
How can I fix this and will it cause issues if I ran dcpromo on the 2003 to demote it without changing the bridgehead for this site?<br />
<br />
Many thanks, <br />

Active directory bridgehead not updating for our site

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).

Windows Server 2003

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

Active Directory
