What does NTSTATUS 0xC000002E (STATUS_INVALID_PORT_ATTRIBUTES) mean?

STATUS_INVALID_PORT_ATTRIBUTES

The port object attributes are not valid for this IPC request

Log the port attributes supplied at creation or connection and compare each field with the native API contract. Correct the invalid object attributes at the caller that constructed them.

This status is about the native port setup contract. It can be returned when object attributes passed to port creation or port attributes passed to a connection request do not match what the kernel expects.

What to inspect

• Inspect the object attributes and port attributes passed to the failing call.
• Check structure sizes and flag combinations.
• Do not confuse this with a TCP port number problem.
