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.
