Hello Andrew,
   I will be looking into this for you. How did you arrive at this conclusion? Do you have a network trace that shows this behavior?

In MS-LSAT it states that:

The RPC server MUST ensure that the RPC_C_AUTHN_NETLOGON security provider (as specified in [MS-RPCE] section and at least RPC_C_AUTHN_LEVEL_INTEGRITY authentication level (as specified in [MS-RPCE] section are used in this RPC message. Otherwise, the RPC server MUST return STATUS_ACCESS_DENIED.

However the behaviour against Windows 2008 is to give an RPC-level fault (access denied), and to prevent any further communication on the named pipe (futher requests get NT_STATUS_PIPE_DISCONNECTED at the trans2 level).

Please update the docs,
