WDSTPC_E_NO_IP4_INTERFACE
WDSTPC_E_NO_IP4_INTERFACE is a server network-interface prerequisite failure. WDS transport sessions expose the network interface name and address used by the server, and transport service policy controls multicast address/network settings; no client callback change can create a missing IPv4 interface on the server.
Inspect server interface and WDS transport network policy
- Verify that the server has an enabled IPv4 interface with the addressing and routing expected for the deployment network.
- Inspect the active WDS network profile, multicast IP address source, and session network interface information.
- Correlate the failure with server configuration changes, NIC disable/teaming changes, or service startup before network readiness.
The WDS management API exposes service-policy settings and per-session network interface data specifically for transport administration. Diagnose this code on the WDS server, not by increasing the client cache or re-registering callbacks. If the server is dual-stack, remember that the error names the absence of an IPv4 interface for this transport path; the existence of IPv6 connectivity does not satisfy that requirement.
