As a tiny aside here, I suspect that: (a) you don't need the cmd.exe
to run xcopy: it's actually an executable; and (b) you might to
double-quote the %s params to xcopy. Neither of these things are
going to be causing the error you report, but just to be helpful...

It is peculiar, assuming you are running exactly the same code, only
with AD setting switched as you describe. ie there's no possibility
that self.c has become something other than a WMI instance?

I'll try to look it at it when I get back to work (which won't be
till Monday now; I'm just back from a week away). If you manage
to fix it in the meantime, please do post back.
