How to Effectively Troubleshoot the COM Server with CLSID Cannot Be Started VSS Error

Encountering the error message regarding the COM server with CLSID indicates a malfunctioning Volume Shadow Copy Service (VSS).This guide offers detailed steps to troubleshoot and resolve this critical issue.

How to Resolve the VSS Error: COM Server with CLSID Cannot Be Started

When faced with the ‘COM server with CLSID cannot be initiated’ VSS error, follow these solutions:

  1. Verify that the COM+ Event System Service is active.
  2. Check if the VSS service is running.
  3. Ensure that the Microsoft Software Shadow Copy Provider Service is operational.
  4. Confirm that any third-party VSS providers are functioning correctly.
  5. Set the Event log size to a maximum of 64MB.
  6. Repair the Windows system image.

Now, let’s delve into each solution.

Step 1: Verify the Status of the COM+ Event System Service

The COM+ Event System Service is crucial for managing events and communication. Check its status by:

  1. Open the Services manager by searching for ‘Services’ in the Windows search bar ( Win + S ).
  2. Locate COM+ Event System, double-click it, and check its status.
  3. If it’s inactive, select ‘Start’ and set the Startup Type to ‘Automatic, ’ then click OK.

Pro Tip: Restart your system after enabling this service to check if the VSS error persists.

Step 2: Check if the VSS Service is Running

The VSS service must be running for backups to function correctly. Ensure its status by:

  1. Open Services by searching for it (Win + S).
  2. Find Volume Shadow Copy, double-click it, and set Startup Type to ‘Manual.’ If it’s stopped, click ‘Start’.
  3. Click OK to save your changes.

Pro Tip: If already active, try restarting this service to resolve any underlying issues.

Step 3: Ensure Microsoft Software Shadow Copy Provider Service is Enabled

This service is vital for the proper functioning of the Volume Shadow Copy service. To ensure it’s operational, follow these steps:

  1. Access Services via the search bar, and locate Microsoft Software Shadow Copy Provider.
  2. Double-click it and ensure the Startup Type is set to ‘Manual’; click OK.

Step 4: Verify Third-Party VSS Providers Functionality

Investigating third-party VSS providers is key as they play a role in VSS operations. Follow these actions:

  1. Press Win + R to open the Run dialog, type cmd, and hit Ctrl + Shift + Enter to launch Command Prompt as an administrator.
  2. To list the installed VSS providers, input the command: vssadmin list providers
  3. To attempt creating a backup, run: vssadmin create shadow

Step 5: Set Event Log Size to Maximum 64MB

Modifying the Event Log size can enhance VSS operations. Here’s how to make this adjustment:

  1. Open Event Viewer by searching for it in Windows, then navigate to ‘Windows Logs.’
  2. Select an Event Log larger than 65MB, right-click it, and choose ‘Properties.’
  3. In the General tab, set the maximum log size to 64000KB or less, then click ‘Clear Log.’ Accept the confirmation and press OK.

Pro Tip: Clearing old logs can help improve performance and avoid conflicts.

Step 6: Repair the Windows System Image

Corrupted system files can lead to VSS issues. The DISM tool can help refresh and repair these files:

To run DISM, open Command Prompt as an administrator and enter:

dism /online /cleanup-image /restorehealth

This command repairs any inconsistencies within the Windows system image.

Additional Tips

  • Always back up critical data before applying system changes.
  • Regularly check for Windows updates to ensure all components are functioning correctly.
  • Consider seeking professional help for advanced troubleshooting if issues persist.

Summary

The ‘COM server with CLSID cannot be started’ VSS error can significantly impact backup processes. By following the outlined procedures, including checking service statuses and adjusting settings, you can effectively troubleshoot and resolve this issue.

Conclusion

Addressing VSS errors requires a systematic approach to check and configure various services. Consistent monitoring and maintenance can prevent these errors from disrupting critical backup operations, ensuring your data remains safe and accessible.
