3.5.4 Message Processing Events and Sequencing Rules

This protocol asks the RPC runtime to perform a strict NDR data consistency check at target level 6.0 for all methods unless otherwise specified, as defined in [MS-RPCE] section 1.3.

When a method completes, the values returned by RPC MUST be returned unmodified to the upper layer. The methods MAY throw an exception and the Terminal Services client MUST handle these exceptions by returning the unmodified exception code to the upper layer.
