Summary

Microsoft Distributed Transaction Coordinator Service Startup

The Microsoft Distributed Transaction Coordinator service (MSDTC) coordinates transactions, regardless of failures that may occur during the process, so that the work is committed as a single transaction even if the work spans multiple resource managers on multiple computers.

MSDTC is a Windows service. By default, the service is configured as a manual service rather than as an automatic service. However, most applications demand-start the service as needed. If necessary, the administrator can start the service with the Services administrative tool.

Causes

Either in low memory condition or missing files for MSDTC.

Resolutions

Start MSDTC (Diagnoser)

Check the system for a low-memory condition. If a low-memory condition exists, close applications to free system memory.

There may be missing files. Check to ensure that Comres.dll is present by following the steps in 'Confirm that Comres.dll is present in the System32 folder.'

When you have resolved a low-memory condition and ensured that Comres.dll exists, restart MSDTC by following the steps in 'Restart MSDTC.'

Restart MSDTC

The system reports that the Microsoft Distributed Transaction Coordinator service (MSDTC) encountered an invalid Class ID for the Transaction Bridge component.

Administrators

To restart MSDTC:

Click Start, and then click Run.
comexp.msc
Click Services.
The system stops and then restarts MSDTC.

You can alternatively stop and restart the Microsoft Distributed Transaction Coordinator service (MSDTC) using the steps listed below:

Click Start, and then click Command Prompt.
net stop msdtc
net start msdtc

Confirm that Comres.dll is present in the System32 folder

The system could not load the Comres.dll file. An error condition may result if a required file is missing from the System32 folder in the Windows directory or if the file is corrupted.

Administrators

To confirm that the required file Comres.dll is present in the System32 folder:

Right-click Start, and then click Explore.
Navigate to the Windows folder. In the details pane, double-click System32.
comres.dll
If the file is present, it may be corrupted. Restore the file from backup.
If the file is missing, restore it from backup.
