Quick Note Before You Begin

Before diving into fixes, make sure you have the following:

  • Administrator access: You will need admin rights to perform many of the steps.
  • Backup: Always back up important data to avoid accidental loss.
  • Windows Updates: Ensure your Windows 11 is up to date as some fixes depend on system patches.
  • Basic knowledge of Task Manager and Command Prompt: Don’t worry, we’ll guide you through these.

Step 1: Restart the msmdsrv.exe Service

Sometimes, the error appears due to a temporary glitch or conflict. Restarting the service can often resolve it.

  1. Press Ctrl + Shift + Esc to open the Task Manager.
  2. Go to the Services tab and look for msmdsrv or SQL Server Analysis Services.
  3. Right-click the service and select Restart.
  4. If the service isn’t running, select Start instead.

Restarting the service refreshes it and clears minor issues without making deeper system changes.

Step 2: Check for Windows and SQL Server Updates

Outdated software can cause compatibility issues leading to errors like msmdsrv.exe malfunctioning.

  1. Open Settings by pressing Windows + I.
  2. Click on Windows Update and then Check for updates.
  3. Install any available updates and restart your computer if prompted.
  4. Next, open your SQL Server Management Studio (SSMS) or SQL Server Installation Center.
  5. Check for updates related to SQL Server Analysis Services and apply them.

Keeping your system and SQL Server components updated fixes bugs and enhances stability.

Step 3: Run System File Checker (SFC) Scan

Corrupted system files can cause the service to fail. Windows has a built-in tool called System File Checker that can repair damaged files.

  1. Press Windows + S, type cmd, then right-click Command Prompt and select Run as administrator.
  2. In the command window, type the following and press Enter:
sfc /scannow

The scan will take some time. It automatically detects and repairs corrupted files. After completion, restart your PC and check if the error persists.

Step 4: Verify SQL Server Analysis Services Configuration

Incorrect service configuration can lead to errors. Checking the settings ensures everything is set up correctly.

  1. Open Services (press Windows + R, type services.msc, and hit Enter).
  2. Locate SQL Server Analysis Services (MSOLAP) in the list.
  3. Right-click and select Properties.
  4. On the Log On tab, ensure the service is running under the correct user account (usually Local System account or a domain account as per your setup).
  5. Switch to the Recovery tab and set the service to restart automatically on failure. This helps recover from unexpected crashes.
  6. Click OK and restart the service.

This step ensures the service runs smoothly with proper permissions and recovery options.

Step 5: Reinstall SQL Server Analysis Services

If none of the above steps work, reinstalling the service can fix deep-rooted problems.

  1. Open Settings > Apps > Installed apps (or Add or Remove Programs).
  2. Find Microsoft SQL Server Analysis Services or the full SQL Server package.
  3. Click Uninstall and follow the prompts.
  4. After uninstalling, download the latest version of SQL Server from the official Microsoft website.
  5. Install it carefully, ensuring the Analysis Services feature is selected during setup.
  6. Restart your computer after installation.

This fresh installation replaces corrupted or missing files and resets the service configuration.

Alternative Method: Use Event Viewer to Diagnose

If you want to dig deeper into what causes the error, use Event Viewer to check detailed error logs.

  1. Press Windows + X and select Event Viewer.
  2. Go to Windows Logs > Application.
  3. Look for error entries related to msmdsrv.exe or Analysis Services around the time the error appeared.
  4. Note down the error codes or descriptions for further online research or support queries.

This method helps identify specific issues, such as permission problems or resource conflicts.
