My understanding is that MS assured people 'NTSTATUS is only for NT ->
NT, you just won't need them' ;-)

Win32 32-bit status codes are different to NTSTATUS codes. We use
WERRORs in the printing subsystem, and have conversion tables for them
too..
On the subject of error conversion: The 'NTSTATUS -> DOS' table is
pretty solid - due to it being extracted almost directly from an NT
table (over the wire, naturally). The other tables are much less robust
- and a glance there are certainly error codes that don't mach up. DOS
-> NTSTATUS in particular.
(We need bright ideas on extracting them).

Some clients expect NTSTATUS error codes on some packets - and don't
behave when they don't get them.
They also provide a *much* richer functionality and allow a much greater
range of errors to be expressed.

A newer list could probably be generated by the same mechinism. The
best available is found on Win2k - but we like keeping at arms length
from that stuff.
