Hello
The error “Remote procedure call was cancelled. Error 8007071a” typically occurs when trying to force a Group Policy update from the Domain Controller. This error can be caused by several factors, including issues with firewall settings, network adapters, or security software blocking necessary ports.
Here are some potential solutions:
Check Firewall Settings: Make sure that Remote Scheduled Task Management (RPC), Remote Scheduled Task Management (RPC-EPMAP), and Windows Management Instrumentation (WMI-In) are allowed in Inbound Rules. You can set this within Group Policy.
Check Security Software: If you’re using security software like Symantec Endpoint Protection, make sure it’s not blocking ports 135 and 445. In one case, it was found that Symantec was blocking these ports, preventing the connection.
Update Network Adapters: Outdated network adapters can sometimes cause this issue. Make sure your network adapters are up-to-date.
Increase the Default Timeout Limit in the Registry: The default timeout settings for RPC on Windows systems can sometimes cause this error. You can manually increase the default timeout limit in the registry.
Enable PMTU Black Hole Detection: This can be manually enabled on Windows-based hosts.
Verify the Network Binding Order: Incorrect network binding order can sometimes cause this issue. Make sure to verify the network binding order.
Remember to always create a backup before making changes to your system settings or registry.
