Applicable WMI Error Codes

• 0x8004100E - Invalid Namespace

Overview

This error occurs when the specified WMI namespace is unavailable, corrupted, or when the required WMI provider is not properly registered during monitor addition or data collection.

Common Causes

• Incorrect or unavailable WMI namespace.
• Corrupted WMI repository.
• Missing or unregistered WMI provider.
• Corrupted or missing MOF files.
• Application-specific WMI namespaces are not installed (for example: SQL Server, IIS, Cluster, or BitLocker).
• WMI provider registration issues.
• Namespace mismatch caused by application version differences.
• Corrupted WMI service or repository.
• Incomplete application installation or upgrade.
• Firewall or DCOM communication issues during remote WMI access.

Resolution Steps

1. Validate the Namespace Using WBEMTEST

1. Get the namespace by referring to the following KB: Namespace & WMI Class

2. Try running the query directly in the wbemtest tool on the Applications Manager server by connecting to the remote server.

3. Refer to the steps under the section "Checking connectivity with WMI Tester" for instructions on using the wbemtest tool.
   

Note: If the namespace connection fails with error 0x8004100E, the namespace is either unavailable, corrupted, or not properly registered.

2. Re-build WMI Repository

Refer to the KB for detailed steps about WMI Reconstruction.

3. Re-register Application-Specific WMI Providers

For application-specific namespaces such as Cluster services, re-register the required WMI provider and MOF files.

Example for Cluster namespace:

regsvr32 -s C:\Windows\System32\wbem\ClusWMI.dll

mofcomp C:\Windows\System32\wbem\clusWMI.mof

4. Verify Firewall Configuration

Ensure the following are allowed through Windows Firewall and network firewall:

• TCP Port 135 (RPC Endpoint Mapper)
• WMI service communication
• Dynamic RPC Ports

Enable the predefined firewall rules mentioned in the "The RPC server is unavailable" KB.

5. Restart the WMI Service

Run the following commands on the target server:

net stop winmgmt /y

net start winmgmt

Contact Support

When contacting support, provide the following:

• Screenshots of all the troubleshooting steps performed and their results.
• Screenshot of the WBEMTEST error message or result.
• Validate the WMI connection using both the hostname and IP address of the target server, and identify which one succeeds in your environment.
• If only one method succeeds, update the monitor using the Update Hostname/IP option and verify whether the issue is resolved.
• Enable Print all log by navigating to Settings → Logging. Perform a manual poll for the affected Windows monitor.
• Generate a Support Information File from Applications Manager after the manual poll.
