Symptoms
When a replica server is removed from a View Cluster, you experience these symptoms:
Deleted connection still exists in the Active Directory Lightweight Directory Services (AD LDS) database.In the Windows Event log files, you see errors similar to: Ownership of the following FSMO role is set to a server which is deleted or does not exist. Operations which require contacting a FSMO operation master will fail until this condition is corrected. FSMO Role: CN=Schema,CN=Configuration,CN={D4E0F27F-C0C7-4557-A872-41BAFD4A6EA4} FSMO Server DN: CN=NTDS Settings\0ADEL:ec16d5ea-cf2e-47b9-9af2-85cb4ad89e1a,CN=ViewConServer06$VMwareVDMDS\0ADEL:31cbfc83-acec-4143-8851-7f4a99a3bf5e,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,CN={D4E0F27F-C0C7-4557-A872-41BAFD4A6EA4}
Cause
This issue occurs when a user removes a replica server from the View cluster incorrectly and the Active Directory has schema master role on that machine, which has been removed.
Resolution
To resolve this issue, run the vdmadmin command to remove the deleted connection. For more information on removing the deleted connection, see Removing a standard (replica) connection server or a security server from a cluster of connection/security servers (1010153).
After removing the deleted connection, verify if all connection servers are replicating with each other. For more information, see Forcing replication between ADAM databases (1021805).
If this issue still persists, seize the schema master role:
To seize the schema master role
To open the command prompt:
Click Start.Right-click Command Prompt and then click Run as administrator.
In the command prompt, run this command: dsmgmt In the dsmgmt command prompt, run this command: roles In the fsmo maintenance command prompt, run this command: connections In the server connections command prompt, run this command: connect to server computername:portnumber where computername:portnumber is the computer name and communications port number of the AD LDS instance that you want to use as the new schema master. In the server connections command prompt, run this command: quit In the fsmo maintenance command prompt, run this command: seize schema masterIn the fsmo maintenance command prompt, run this command: seize naming master
To check who owns the FSMO roles, you need to run these commands in sequence:
dsmgmt <enter>roles <enter>connections <enter>connect to server servername:389 <enter>quit <enter>select operation target <enter>list roles for connected server <enter> Note: This should list who owns the FSMO roles.
