I'm trying to upgrade an exchange 2013 server to CU18, but it's currently failing.

The error is...

The server side error is: 0x21a2 The FSMO role ownership could not be verified because its directory partition has not replicated successfully with at least one replication partner.

Now this is a standalone server, however it originally did have a partner, but we ended up scrapping that.

I can see in active directory sites and services that it lists both itself and the server that was going to be its replica.

Can i just right click and delete that server from sites and services to proceed does anyone know?

I've had a bit of a search and everything suggests that i fix the replication before continuing... well thats easier said than done as the server that was going to be the replica doesnt exist any more.

any help appriciated.

    Just to confirm, there is a server showing up in Sites and Services that doesn't exist right now? – Todd Wilcox Nov 20 '17 at 21:11
  • exactly that... correct – John Nov 20 '17 at 21:13
  • If you aren't completely comfortable working in adsiedit, you may want to get a consultant. If you are, time for some manual cleanup – Jacob Evans Nov 20 '17 at 21:16

Looks like you'll want to do the following for the server that has been removed:

https://blogs.technet.microsoft.com/canitpro/2016/02/17/step-by-step-removing-a-domain-controller-server-manually/

Step 1: Cleaning up metadata via Active Directory Users and Computers

  1. Log in to DC server as Domain/Enterprise administrator and navigate to Server Manager > Tools > Active Directory Users and Computers
  2. Expand the Domain > Domain Controllers
  3. Right click on the DC server that need to remove manually and click delete
  4. In next dialog box, click yes to confirm
  5. In next dialog box, select This Domain Controller is permanently offline and can no longer be demoted using the Active Directory Domain Services Installation Wizard (DCPROMO) and click Delete
  6. If the domain controller is global catalog server, in next window click yes to continue with deletion
  7. If the domain controller holds any FSMO roles in next window, click ok to move them to the domain controller which is available

Step 2: Cleaning up the DC server instance from the Active Directory Sites and Services

  1. Go to Server manager > Tools > Active Directory Sites and Services
  2. Expand the Sites and go to the server which need to remove
  3. Right click and click Delete
  4. In next window click yes to confirm

Step 3: Clean up metadata using ntdsutil

NOTE: Windows Server 2003 or earlier used ntdsutil and was bit of challenge but this was later simplified

  1. Right Click on Start > Command Prompt (admin)
  2. Type ntdsutil and enter
  3. Then metadata cleanup
  4. Next type remove selected server <servername>, replace <servername> with DC server to remove
  5. In warning window click yes to proceed
  6. Execute quit command twice
  • C:\setup>ntdsutil ntdsutil: metadata cleanup metadata cleanup: remove selected server HOSTEX-2 Binding to localhost ... Connected to localhost using credentials of locally logged on user. LDAP error 0x22(34 (Invalid DN Syntax). Ldap extended error message is 0000208F: NameErr: DSID-03100225, problem 2006 (B AD_NAME), data 8350, best match of: 'CN=Ntds Settings,HOSTEX-2' Win32 error returned is 0x208f(The object name has bad syntax.) ) Unable to determine the domain hosted by the Active Directory Domain Controller (5). Please use the connection menu to specify it. – John Nov 20 '17 at 21:55
  • @John Trouble running NTDSUTIL could be a separate question. I would definitely try logging on to the currently running domain controller, running command prompt as an administrator and then trying NTDSUTIL again. If that's how you already did it, then either google that error or ask a new question about it. – Todd Wilcox Nov 20 '17 at 21:59
