STATUS_CLIENT_SERVER_PARAMETERS_INVALID

Inspect the marshaled request layout and the shared parameter-window limits

STATUS_CLIENT_SERVER_PARAMETERS_INVALID explicitly refers to parameters passed through a client/server shared-memory window. The failure is therefore more specific than a normal bad argument: the server rejected the parameter representation or amount of data presented in the shared communication region. This class of boundary requires the producer and consumer to agree on offsets, lengths, alignment, and the exact request layout.

The NTSTATUS catalog warns that too much data can have been placed in the shared-memory window. When investigating, preserve the raw request header and size fields before the server or compatibility layer normalizes them. Validate every embedded offset as an offset into the declared region rather than as an arbitrary process pointer, and prove that offset + length cannot overflow before checking the region boundary.

Version skew is another useful line of inquiry because a client and server built around different structure layouts can interpret the same bytes differently. Capture both component versions and the operation identifier. Do not solve the problem by simply increasing a destination allocation if the shared window has a fixed protocol limit; the request may need to be split, use a different transfer path, or encode less data according to the actual contract.

What to inspect

  • Dump the operation ID, total window size, parameter count, and every offset/length pair.
  • Validate arithmetic for wraparound before checking whether a range lies inside the shared region.
  • Compare client and server structure versions when the same request fails only across mixed component builds.
