I wouldn't consider doing that if you've already got
them interoporating: it's a long and winding path to NT
nirvana, and it removes the option of single sign-on...
If it isn't broken, don't fix it!
Plain-text passwords are (i) a security issue and (ii) a
nuisance issue. You deal with them the same way as you
deal with plaintext passwords in Unix.
i) make sure the link between your sites is encrypted or
private. Every packet you send is in plain text: encrypted
passwords encrypts **only** the passwords, not the data.
ii) Give each user (or site sysadmin) a "rescue" floppy
with the .reg files on it. Users will forget, but when
you remind them, they'll have the files handy.
Also, create a [help] share with public = yes,
and put a copy of the .reg files and a RUN_ME.BAT
Finally, give each user a startup file that sets the
registry flags: then all they have to do is connect to
[help] and they'll get the flags set automagically (;-))

Not if nis+ works...

Not at all

No, it checks against PDCs and BDCs, which you should have
