RPC_NT_NO_PRINC_NAME
Missing RPC server principal name
RPC_NT_NO_PRINC_NAME belongs to the Windows RPC runtime NTSTATUS facility. For RPC_NT_NO_PRINC_NAME, mS-RPCE extends the DCE/RPC model: generated stubs marshal parameters, the runtime binds to an endpoint and protocol sequence, and security or transport failures can be returned as RPC facility status values.
This status is tied to authenticated RPC. A principal name identifies the server identity expected by the client and used by the security package during authentication.
The failure is not fixed by changing the endpoint alone. Verify how the server registers authentication information and how the client composes the target principal, especially with Kerberos, SPNs, service aliases, and cross-domain access.
What to check for RPC_NT_NO_PRINC_NAME
- Check server calls that register authentication services and principal names.
- Verify the client target principal or SPN when Kerberos is used.
- Look for hostname aliases, load balancers, or CNAMEs that make the expected server principal differ from the actual one.
