This problem with DOS 4.x printing out 'Illegal Function' or something like
that is quite common on a lot of LANs until they upgrade.

There were some new calls added to INT21 AH=57 set file/date time.  These
are totally undocumented but are required by DIR.  On our LAN we take 
over
function 57 except we pass along these new calls to DOS since we couldn't
figure out what they did.  And believe me we tried.  I have a very long
list of undocumented functions which we have created during the development of
a FILE SHAREING LAN.
