RPC_S_NO_MORE_BINDINGS

The binding vector or lookup sequence has been exhausted

RPC_S_NO_MORE_BINDINGS is an enumeration result: an RPC binding inquiry or lookup has no additional binding handles to return. It does not by itself say that every returned binding is unreachable, nor that the server has no interfaces. The caller has reached the end of the current binding set.

Count the bindings already returned and log their protocol sequences and endpoints. If zero were produced, inspect server binding creation and interface registration; if several were produced, the status may be a normal terminator that application code should not report as a fatal transport failure. Free each binding vector and inquiry context according to the API contract.

What to inspect

  • Distinguish end-of-enumeration from failure of a particular binding.
  • Inspect which protocol sequences the server actually registered.
  • Release inquiry contexts and binding vectors on every exit path.
