RPC_S_INCOMPLETE_NAME

This is a namespace entry-name error, not an incomplete string binding

RPC_S_INCOMPLETE_NAME arises in RPC name-service operations when an entry name does not form a complete name in the selected namespace syntax. It should not be confused with RPC_S_BINDING_INCOMPLETE, which concerns missing components of a server binding.

DCE RPC name-service APIs use entry names for publishing and locating binding information. A partial or context-relative name can be invalid when the operation requires a complete entry.

What to inspect

Log the exact namespace entry string and NameSyntax parameter supplied to the failing RpcNs* function.
Check whether code truncated the entry while joining a namespace prefix and application-specific service name.
Keep namespace names separate from DNS host names and RPC string bindings; they are parsed by different APIs.
If the application supports relative names, verify which namespace context or expansion step is required before export or lookup.

Adding an endpoint or changing an interface UUID will not complete a namespace name. Fix the entry-name construction and selected syntax first.
