WMI Namespace and Provider Errors

WMI Namespace and Provider Errors

Applicable WMI Error Codes

  • 0x8004100E - Invalid Namespace

Overview

This error occurs when the specified WMI namespace cannot be found or accessed during monitor addition or data collection. An incorrect namespace, a missing or unregistered WMI provider, or issues with the WMI repository may cause this.

Common Causes

  • Incorrect or unavailable WMI namespace.
  • Corrupted or damaged WMI repository or related WMI components.
  • Missing, unregistered, or incorrectly registered WMI provider.
  • Corrupted or missing MOF files.
  • The application or Windows feature providing the required WMI namespace is not installed or configured (for example, SQL Server, IIS, Cluster, or BitLocker).
  • Namespace mismatch caused by application version differences.
  • Incomplete application installation or upgrade.
  • Remote WMI connectivity issues that prevent successful access to the required namespace.

Resolution Steps

1. Validate the Namespace Using WBEMTEST

  1. Refer to the Namespace & WMI Class KB to identify the namespace and WMI class associated with the affected metric.

  2. Open WBEMTEST on the Applications Manager server and connect to the target server using the required namespace.

  3. Execute the corresponding WQL query.

  4. Refer to the Verify WMI Connectivity Using WBEMTEST section for detailed instructions.

NotesNote: If the namespace connection fails with error 0x8004100E, verify that the namespace exists on the target server and that the required WMI provider is installed and properly registered.

2. Rebuild WMI Repository
  1. Refer to the Reconstruct / Rebuild WMI Class KB for detailed instructions on repairing or rebuilding the WMI repository.
3. Re-register Application-Specific WMI Providers
  1. For application-specific namespaces such as Cluster services, verify that the required WMI provider is installed and properly registered. If required, re-register the provider and associated MOF files using the procedure recommended for that application or Windows feature.

Example for Cluster namespace:

Quote
regsvr32 -s C:\Windows\System32\wbem\ClusWMI.dll
mofcomp C:\Windows\System32\wbem\clusWMI.mof
4. Verify Firewall Configuration
If the namespace is available locally but cannot be accessed remotely from Applications Manager, verify the firewall and DCOM 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 firewall rules mentioned in the "The RPC server is unavailable" KB.

5. Restart the WMI Service
  1. Run the following commands on the target server:
Quote
net stop winmgmt /y
net start winmgmt
InfoContact Support

When contacting support, provide the following:

  • Screenshots of the relevant troubleshooting steps performed and their results.
  • Screenshot of the WBEMTEST error message or result.
  • Validate the WMI connection using both the target server's hostname and IP address, and identify which 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 logs by navigating to Settings → Logging. Perform a manual poll for the affected Windows monitor.
  • Generate a Support Information File (SIF) from Applications Manager after reproducing the issue and performing a manual poll.
