Windows Management Instrumentation (WMI) is a core component of the Windows operating system used to manage data and operations. The VMS depends on WMI to pull hardware identifiers from the underlying system to generate a unique Hardware ID (HWID).

In certain scenarios, most commonly following a major Windows Update, the WMI repository can become corrupted. When this happens, the VMS can no longer correctly read the system components. This results in a change to the Hardware ID, causing the software to believe it is running on a different machine. Consequently, your licenses will appear as "Server not found" or become unavailable, as they are locked to the previous Hardware ID.

Troubleshooting and Manual Repair

If you suspect WMI corruption is the cause of your licensing issues, you can manually verify and repair the repository. Below are the steps to perform a manual reset of the WMI environment:

1. Check Repository Health: Open the Command Prompt as an Administrator and run:

   winmgmt /verifyrepository

   If the result returns "Repository is inconsistent," a repair is required.

2. Stop Management Services: To perform a deep repair, you must first stop the Windows Management Instrumentation service. This often requires stopping dependent services like IP Helper and Security Center first.

3. Perform a Consistency Check: Run winmgmt /salvagerepository. This command attempts to rebuild the database if it detects corruption.

4. The "Hard" Reset (If Salvage Fails): If the repository remains broken, the Repository folder located in C:\Windows\System32\wbem\ must be renamed (e.g., to repository.old). After renaming, restart the WMI services or reboot the computer. Windows will then automatically recreate the database from scratch.

5. Re-register Components: Finally, you may need to re-register the WMI DLLs and recompile the .mof files within the wbem directory to ensure all providers are correctly linked to the new database.

Automated Fix

Because the manual steps involve stopping system services and navigating system folders, we have created an automated script to simplify the process.

The wmiRepair.bat script, which you can download at the bottom of this article, performs the following actions:

• Stops the WMI Service and all related dependencies.

• Backs up and resets the WMI repository.

• Re-registers all necessary WMI components and libraries.

• Restarts the required services.

Instructions:

1. Download the wmiRepair.bat file attached below.

2. Right-click the file and select Run as Administrator.

3. Once the script finishes, restart your Server computer.

4. Open the VMS and check if the Hardware ID has reverted to its original state and if licenses are active.
