MDT deployment update error on Windows 2012 R2.

Question

An error occurred while trying to execute the command. Error Code: 0xC1210107 Error Description: The specified namespace already exists.

䔊楸⁴潣敤㴠ⴠ〱㐵〸㘱㜵 Multicast namespace “DeploymentShare$” already exists.

=== Processing complete ===

MDT does not know how to put the Multicast Transmission link in WDS. The solution is to remove the link. Run the deploymentshare update and a new link will be created.

"Do i just remove the link in WDS, and how sure am i that the link will be created again by MDT and work?"

Hello,

You can follow these steps to resolve the issue:

Open the Windows Deployment Services (WDS) console on the server where MDT is installed.

Expand the server node and navigate to the Multicast Transmissions folder.

Locate the existing multicast transmission link named “DeploymentShare$” and delete it. Right-click on the link and select Delete.

Once the link is removed, return to the MDT deployment share.

Open the Deployment Workbench and navigate to the properties of the deployment share giving the error.

Click on the “Rules” tab and edit the bootstrap.ini file.

Add or modify the following entry:

SkipBDDWelcome=YES

Save the changes and close the properties window.

Open a Command Prompt with Administrator privileges.

Change directory to the location where your deployment share is located. For example, if your deployment share is stored on the D drive, you can use the command:

cd /d D:\DeploymentShare\Scripts

Run the deploymentshare update command to recreate the multicast transmission link. Use the following command:

DeploymentShare\Scripts\bootstrap.ini /configuration:“D:\DeploymentShare”`

Wait for the process to complete and verify that the multicast transmission link is created successfully.

By following these steps, you remove the existing multicast transmission link in WDS and instruct MDT to recreate it during the deploymentshare update process.
