I think MS just did us (and themselves) a disservice.

Yes, but it's not the telnet client which detects attempted root login :)

It's the server...

It's often useful to do this when testing network connectivity for
accounts other than your own, or if you need quick temporary access to
resources your own account cannot access.  There are other situations
where processes may need to access shares using different sets of

It's not "fixed" under Terminal Server per se, it's just handled at a
lower level.

(I would hesitate to use the word "fixed" when discussing ANYTHING
 about NT Terminal Server.  ;-) )

Even on a regular NT desktop machine, it is possible to multiplex
different sets of credentials on the same SMB connection -- ClearCase
does this, for example (don't know the details). So it's not a hard
and fast rule.

I suspect the limitation is only in the front-end (the GUI and the
"net use" command), not at the API level.  And as I mentioned earlier,
it's not very well implemented (i.e. it apparently only does string
comparisons on the server hostname, not actual name service lookups).

Who knows, maybe they really did slap this on for security reasons and
just didn't think carefully.  It happens.  IIRC, Solaris 2.6 shipped
with non-console root logins (telnet, rlogin, etc) disabled for
security reasons but root FTP connections allowed.  Oops.
