Windows Error - Management Exception – The call was canceled by the message filter (0x80010002)

Overview

The error The call was canceled by the message filter (Exception from HRESULT: 0x80010002) typically indicates a communication breakdown between the Cloudamize ADC and the target server's WMI subsystem. This is primarily caused by WMI issues on the target server or a middleman (network filter) interrupting the call.

Troubleshooting Steps

1. Verify and Restart WMI Services

The first step is to ensure the Windows Management Instrumentation service is healthy on the destination machine.

1. Log in to the Target Server.

2. Open the Services snap-in (services.msc).

3. Locate Windows Management Instrumentation.

4. Check if the service is Running.

5. Even if it is running, Restart the service to clear any hung threads or locked providers.

2. Local WMI Validation (WBEMTest)

If restarting the service does not resolve the issue, test if WMI is functioning locally on the node to rule out a corrupt repository.

1. On the Target Server, open the Run command (Win + R), type wbemtest, and press Enter.

2. Click Connect.

3. In the Namespace box, ensure root\cimv2 is present and click Connect again.

4. If you receive an error here, the WMI repository on the host itself is damaged and requires repair.

3. Network Message Filter Check

The error specifically mentions that the "call was canceled by the message filter."

• Action: Consult with your Network Security team to identify if there are any Layer 7 Firewalls, Intrusion Prevention Systems (IPS), or Deep Packet Inspection (DPI) tools in the network path.

• These "message filters" can sometimes intercept RPC/WMI traffic and cancel the call if they perceive the volume of data as a security risk or a port scan.
