Looking at the code (which you can find here <>), it appears either NetUserGetInfo() or NetUserEnum() is failing. Seems like a strange error message but perhaps it makes more sense in context. Since I cannot reproduce it, I cannot be of more help.

mkgroup doesn't give an error message.  Why mkpasswd does and mkgroup
does not might be pertinent -- don't they use similar mechanisms?  What
do they do different?

Because they are looking for different information. See <>

There's lots of places where error results are printed out without saying
what call they are referring to.  Since I'm not the only one with this
problem, is it possible to have error messages also mention what call
returned the error?  - maybe print out any useful (human interpretable)

It's possible, sure. I expect it's pretty obvious where you might want to make such a change in mkpasswd.c if you're so inclined.

Or are there other programs in windows that would try to print out the same

I.e. say some variant of the "net" or "netsh" commands"?  On linux, I can try
debugging with the 'net' command and it's various outputs, but I don't know
what I'd use here to do the same.

I'm sure. The APIs in use aren't only for Cygwin. I don't know of any utility that you can use, off the top of my head, that would provide better insight than debugging through the code.

I've tried building things from cygwin before and never had any luck just
satisfying the dependencies, so that's been a non-starter for me.

Perhaps it's time to try again. In this case anyway, you wouldn't need to build more than 'mkpasswd'. Shouldn't be too hard if you're used to building any software. Sounds like you've done some of this before but I may be misinterpreting.
