At this point, Dave, it might pay for you to actually create a web page
with the rants and post links... :-p

Roy, the name after the "tee" command is, of course, the name of the file
you'll be overwriting.  In any case, you might want to first get a command
running (without any redirection or pipes), and then redirect it in the
way I showed you.

Dave, you can be sure I've tried the obvious before posting.  It didn't
work for me.  Perhaps the "local domain" (i.e., the current computer)
isn't handled in the same way.

It would have broken other apps as well, just not in such an obviously
detectable way.

"tee" isn't telling you anything, you're seeing the output of "mkpasswd"
(or "mkgroup", as the case may be).

See <http://cygwin.com/cygwin-ug-net/ntsec.html>.

The commands you quoted will have destroyed your /etc/passwd completely.
Try re-running the commands I gave you.

This is a problem.  Are you on the network when you run this command?  If
not, the delay may be mkpasswd waiting for domain controller connections
to time out.

Did you run "mkpasswd -c -l", like I told you?

> Boss AT raid ~
> $ mkpasswd  -l | tee /etc/passwd

This just overwrote /etc/passwd generated in the previous run.

> Boss AT raid ~
> $ mkgroup  -l | tee /etc/passwd

Ditto, and this time it's with the output of mkgroup.

> Boss AT raid ~

> Cannot get PDC, code = 2453

As you see, the primary domain controller is inaccessible.  Do you need to
be on a VPN or something to log in to the domain?
