Resolve

Start the Microsoft Distributed Transaction Coordinator

The event message indicates that the problem might be resolved if you enable the Microsoft Distributed Transaction Coordinator (MS DTC). Determine whether the MS DTC is installed and properly configured. If it is not installed, you can use the Add Roles Wizard to add this role service to the Application Server role.

To perform these procedures, you must have membership in Administrators, or you must have been delegated the appropriate authority.

Determine whether the MS DTC is installed

To determine whether the MS DTC is installed:

  1. Click Start, and then click Run.
  2. Type comexp.msc, and then click OK. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. In the console tree of Component Services, click Services (Local).
  4. Scroll through the list of service names to find Distributed Transaction Coordinator.
  5. Confirm that the status of the service is Started. If the DTC is installed but not started, right-click Distributed Transaction Coordinator, and then click Start.

Check the MS DTC configuration

To check the MS DTC configuration:

  1. In the console tree of Component Services, click Component Services (Local).
  2. Expand Computers, expand My Computer, expand Distributed Transaction Coordinator, right-click Local DTC, and then click Properties.
  3. Click the tabs in the Properties dialog box to confirm that the configuration settings are correct.

Enable the MS DTC if it is not installed

To enable the MS DTC if it is not installed:

  1. Click Start, and then click Server Manager. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  2. Under Roles Summary, click Application Server.
  3. Click Add role services.
  4. On the Select Role Services page, click Distributed Transaction Support. Some role services require the installation of supporting features or role services from other roles. If this is the case, a dialog box appears. Click Add Required Features.
