Upgrading to Encrypted passwords ;-)

This feature is by desing in Windows as sending your default credentials
to any server unencrypted is a HUGE security risk.

Imaging the case wher you have Computer A and Computer B.  Both are
untrusted by the other users.
What you are wanting would go something like this

User C has an administrator account on Computer A and a normal account
on COmputer B.

User C is clever and knows that if he uses the same password on both
computers then D may be able to get access to his account on A

User D only has an administrator account on computer B.

User D is evil and wants an admin account on Computer A

When User C logs on to A he maps a drive on Computer B.
B is only using plaintext passwords.
A sends Cs username to B
A then sends Cs _LOGIN_ password to B unencrypted.  (This is the wrong
A the prompts C for his password to B. (A is then authenticated)

But B can snoop the network and find out A's password for B and gain
access to his machine there.

This is a simplified version of what would happen if Windows did what
you wanted.
Without this B could only get A's password for D. (and every other
computer that A connects to using plaintext passwords if A & B are on
the same subnet)
