Demoting a domain controller with application directory partitions DC=TAPI3Directory

I am replacing an old DC in my active directory. This domain originally had two DC's, and I am replacing one of them with a new one. The new one is already up and running and I have already moved the global catalog and transferred the FSMO roles and moved over DNS and DHCP and set my clients to reference the new server for DNS. I have also moved over all my files and printer shares. Now I am trying to demote the old DC but I keep getting this warning:

this domain controller holds the last replica of the domain of the following application directory partitions:
DC=TAPI3Directory, DC=SFWS, DC=Local

What should I do?

First the TAPI3Directory is used for IP and other telephony services.It is save to delete it but you got to decide that on your own.

to remove it you would have to use Ntdsutil.

This is how to recreate the Directory on your new Domain Controller.
To recreate it after you forcibly remove it follow:

To create a TAPI application directory partition
Verify that the computer is a domain controller and that the Active
Directory directory service is running.

Open Command Prompt.

At the command prompt, type:

tapicfg install /directory: PartitionName [/server:DCName] [/forcedefault]

Value Description
/directory: PartitionName
Required. Specifies the DNS name of the TAPI application directory
partition that is to be created. Note that this name must be a fully
qualified domain name.

/server: DCName
Specifies the DNS name of the domain controller on which the TAPI
application directory partition is to be created. If the domain controller
name is not specified, the name of the local computer is used.

/forcedefault
Specifies that this directory will be the default TAPI application
directory partition for the domain. There can be multiple TAPI application
directory partitions in a domain.

If this application directory partition is the first TAPI application
directory partition created on the domain, it is automatically set as the
default, regardless of whether you use the /forcedefault option.

When you say IP and other telephony services can you give me an example or be more specific? Obviously I use IP addresses in my Active Directory so that's a very broad topic and I have no idea what telephony services are.

Krisdeep

Any telephony service over IP. Example fax

Do I need to create the new application directory partition on the new DC and replicate it from the old DC first?

Are you using IP & telephony service? If yes, you can recreate after removal.
Else,you can safely ignore & do the forceremalal followed by metadata rcleanup.
The TAPI3Directory is used for IP and other telephony services.

You can go ahead & can perform forceremoval followed by metadata cleanup. I don't think any org is using TAPIdirectory for any telephony service,but incase you require it later can recreate using the command.
