VSS Error: Unable to Start COM Server with CLSID

During an image-based backup or following the end of a scheduled backup, upon inspecting the Event Viewer logs, we encountered the following error associated with Event ID 13.

Volume Shadow Copy Service information: The COM Server with CLSID {4e14fba2-2e22-11d1-9964-00c04fbbb345} and name CEventSystem cannot be initiated. [0x8007045b, A system shutdown is in progress.]

Essentially, this VSS error message indicates that the COM Server with CLSID cannot be initiated. In this article, we will explore this issue further and outline potential resolutions.

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

If you encounter the ‘COM server with CLSID cannot be initiated’ VSS error, implement the following 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 64MB maximum.
6. Repair the Windows system image.

Now, let’s delve into each solution.

1] Verify COM+ Event System Service Status

COM+ Event System Service oversees communication and event management between applications. If this service is not active, it can disrupt essential components, including VSS. Here’s how to check its status:

1. Launch the Services manager by searching ‘Services’ in the Windows search bar (Win + S).
2. Scroll down to locate COM+ Event System, double-click it, and view the service status.
3. If it’s not running, click ‘Start’ and set the Startup Type to ‘Automatic,’ then click OK.

Check if the problem still exists after this step.

2] Confirm VSS Service is Active

The issue could arise if the VSS service is disabled. It’s imperative to ensure it is active. Follow these instructions:

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

If the service was already active, restart it and see if the issue resolves.

3] Ensure Microsoft Software Shadow Copy Provider Service is Enabled

Having the Microsoft Software Shadow Copy Provider Service disabled can hinder the Volume Shadow Copy service and cause COM server errors. To make sure this service is active, do the following:

1. Open Services through the Search bar and find Microsoft Software Shadow Copy Provider.
2. Double-click on it and set the Startup Type to ‘Manual,’ then press OK.

4] Check Third-Party VSS Providers’ Functionality

Third-party VSS Providers are crucial for managing VSS operations, and if they’re malfunctioning, it can prevent shadow copies from being created and lead to errors. To check their status, follow these steps:

1. Press Win + R to open the Run dialog, type cmd, and hit Ctrl + Shift + Enter to open Command Prompt with administrator privileges.
2. To view a list of VSS providers installed, enter the command: vssadmin list providers
3. To create a backup copy for all listed providers, run: vssadmin create shadow

This should assist in resolving the issue.

5] Set Event Log Size to Maximum 64MB

If you’re still experiencing the error, consider adjusting the Event Log size to a maximum of 64MB. This action increases the Event log size, ensuring it does not impede Volume Shadow Copy operations, which depend on logging. Here’s how you can do it:

1. Open Event Viewer by searching for it in Windows, then select ‘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.’ Confirm the action if prompted, and press OK.

This approach should help you.

6] Repair Windows System Image

VSS errors may signal a corrupt Windows system image. To address this, running the DISM tool can help refresh the system files and rectify the issue. Utilizing additional options with DISM can also fix inconsistencies or corruption.

By following the solutions outlined above, you should be able to resolve the problem effectively.

How to Resolve VSS Errors?

To tackle VSS errors, begin by ensuring that critical services like Volume Shadow Copy and Microsoft Software Shadow Copy Provider are operational. The earlier sections provide detailed instructions on executing these solutions.

How to Enable VSS on Windows Server?

To activate the Volume Shadow Copy Service (VSS) on a Windows server, press Win + S, type ‘Services,’ and open it. Locate ‘Volume Shadow Copy,’ double-click it, and change the Startup Type to ‘Manual,’ then click OK.
