How to Fix “Server Not Register DCOM Within Required Timeout” Error on Windows 11

If you are using Windows 11 and encounter the “Server Not Register DCOM Within Required Timeout” error, it can disrupt the smooth functioning of your system. This error typically relates to communication problems between applications and system components.

Understanding why this happens and how to fix it can help you restore normal operations quickly. The good news is that most solutions are straightforward and do not require advanced technical knowledge.

In this guide, we will walk you through simple methods to resolve this error step-by-step. Whether you are a beginner or experienced user, these instructions will help you troubleshoot effectively.

Let’s start with some quick checks before diving into detailed fixes.

Quick Note: Prerequisites and Initial Checks

  • Check for Windows Updates: Sometimes, this error can occur due to outdated system files. Ensure your Windows 11 is up to date by going to Settings > Windows Update.
  • Restart Your Computer: A simple reboot can clear temporary issues causing the error.
  • Note the Exact Error Time: Knowing when the error appears helps in diagnosing related services or applications.
  • Ensure You Have Administrative Access: Fixing DCOM errors often requires admin rights, so make sure you are logged in as an administrator.

Step 1: Restart the Distributed COM Service

The DCOM service is responsible for managing communication between software components. Restarting it can clear any temporary glitches.

  1. Press Windows + R on your keyboard to open the Run dialog box.
  2. Type services.msc and press Enter.
  3. In the Services window, scroll down and find Distributed Transaction Coordinator.
  4. Right-click it and select Restart. If the option is grayed out, choose Start.
  5. Close the Services window and check if the error still occurs.

Why this matters: Restarting the service resets its state and can resolve timing issues causing the timeout.

Step 2: Adjust DCOM Permissions

Improper permissions can prevent the server from registering within the required timeout. Adjusting these permissions can help.

  1. Press Windows + R, type dcomcnfg, and hit Enter. This opens the Component Services window.
  2. In the left pane, expand Component Services > Computers > My Computer.
  3. Right-click My Computer and select Properties.
  4. Go to the COM Security tab.
  5. Under Launch and Activation Permissions, click Edit Limits.
  6. Make sure Administrators and System have Local Launch, Remote Launch, Local Activation, and Remote Activation allowed.
  7. Click OK to save changes.
  8. Restart your computer to apply these changes.

Why this matters: Permissions control which users and system components can communicate via DCOM. Correct settings ensure smooth registration.

Step 3: Check the Event Viewer for Related Errors

The Event Viewer logs detailed information about system activities and errors. It helps identify the exact cause of the timeout.

  1. Press Windows + X and select Event Viewer.
  2. In the left pane, expand Windows Logs and click System.
  3. Look for errors with the source DistributedCOM or Event ID 10016 (commonly related to this issue).
  4. Note down the details such as the CLSID and APPID from the error description.

These details help in applying targeted fixes, such as modifying registry permissions.

Step 4: Modify Registry Permissions (Advanced)

This step is for users comfortable with editing the Windows Registry. Incorrect changes can harm your system, so back up the registry first.

  1. Press Windows + R, type regedit, and press Enter.
  2. Navigate to the following path based on the CLSID you found in the Event Viewer:
    HKEY_CLASSES_ROOTCLSID{Your-CLSID}
  3. Right-click the CLSID folder and select Permissions.
  4. Click Advanced and then Change next to Owner.
  5. Set the owner to Administrators and click OK.
  6. Give Administrators full control permissions.
  7. Repeat these steps for the corresponding APPID at:
    HKEY_CLASSES_ROOTAppID{Your-APPID}
  8. Close the Registry Editor and restart your PC.

Why this matters: Some DCOM errors occur because the system cannot access specific registry keys due to permission restrictions.

Alternative Method: Use System File Checker (SFC) Scan

Corrupted system files can lead to DCOM errors. Running an SFC scan repairs these files automatically.

  1. Press Windows + X and select Windows Terminal (Admin) or Command Prompt (Admin).
  2. Type the following command and press Enter: 
    sfc /scannow
  3. Wait for the process to complete. It may take some time.
  4. If any corrupted files are fixed, restart your computer.

This method is safe and often resolves many underlying system issues.
