ERROR_WMI_GUID_DISCONNECTED - 4207 (0x106F)
The WMI data block is no longer available.
Updated: Feb 21, 2026
Technical Background
The ERROR_WMI_GUID_DISCONNECTED error code, with the numeric value 4207 and hexadecimal representation 0x106F, is a specific error indicating that a WMI data block has become unavailable. This error typically arises when there is an issue with the Windows Management Instrumentation (WMI) service or its associated components.
Error Details
The ERROR_WMI_GUID_DISCONNECTED error suggests that a particular WMI provider, identified by a specific GUID, has encountered a disconnection from the WMI infrastructure. This can occur due to various reasons such as hardware issues, software conflicts, or configuration problems within the system.
Common Causes
- Invalid Parameter Values: Incorrect parameters passed during WMI operations may lead to this error.
- Incorrect Object Type: Using an incorrect object type in WMI queries might result in disconnection errors.
- Exceeding Limits: Attempting to access a large number of objects or exceeding system limits can trigger this error.
- Corrupted Data: Corrupted data within the WMI repository could cause the provider to disconnect.
- Unsupported Operations: Performing operations that are not supported by certain WMI providers might lead to disconnection.
Real-World Context
This error is commonly encountered in scenarios where system administrators or developers need to query or manage hardware, services, and other system components using WMI. It can impact the performance and reliability of monitoring tools and scripts that rely on WMI for data retrieval.
Is This Error Critical?
The criticality of this error depends on the specific context in which it occurs. In general, if the error is related to a core system component or service, it may have significant implications for system stability and performance.
How to Diagnose
- Review Operation Context: Examine the environment and conditions under which the error occurred.
- Validate Parameters: Ensure that all parameters used in WMI operations are correct and valid.
- Confirm Object Types: Verify that the object types being queried or manipulated are appropriate for the operation.
- Verify Input Data: Check for any corrupted data within the WMI repository.
- Check Limits or Constraints: Confirm that system limits have not been exceeded.
How to Resolve
- Correct Parameter Usage: Ensure all parameters used in WMI operations are correct and valid.
- Adjust Operation Context: Modify the operation context if necessary, such as adjusting query filters or object types.
- Restore Data: If data corruption is suspected, restore from a backup or repair the repository.
- Retry Operation with Valid Inputs: Attempt to perform the operation again using valid inputs.
Developer Notes
Developers should be cautious when handling WMI operations and ensure that all parameters are validated before execution. Additionally, they should implement error handling mechanisms to gracefully manage such errors in their applications.
Related Errors

FAQ
Q: What does the ERROR_WMI_GUID_DISCONNECTED error mean?
A: It indicates that a specific WMI provider has become disconnected from the system infrastructure, possibly due to invalid parameters or corrupted data.
Q: How can I prevent this error?
A: Ensure all WMI operations use valid parameters and object types. Regularly back up and verify the integrity of the WMI repository.
Summary
The ERROR_WMI_GUID_DISCONNECTED error is a specific indication that a particular WMI provider has become disconnected, likely due to issues with parameters, data corruption, or unsupported operations. By understanding its causes and implementing appropriate diagnostics and resolutions, developers can mitigate this issue and ensure the reliability of their applications.
