How to troubleshoot error 0x800706ba

RPC failures may be local or remote. Determine which endpoint is unavailable before changing services or firewall rules.

1

Determine whether the endpoint is local or remote

Record the application, target computer, service, and action that returned RPC unavailable.

2

Check service and name resolution

Confirm RPC-related services are available and that the target name resolves to the expected address. Test reachability using approved network tools.

3

Review firewall policy and event logs

Check approved firewall policy and Event Viewer for the unavailable endpoint. On managed networks, involve the administrator rather than opening broad rules.

Before advanced repair: Do not open broad firewall ranges or restart core services on production systems without understanding the affected endpoint.
