We prefer *attached* output.  Anyway, I agree with Chris's comments, even 
though it's not obvious that this is the problem.  Look for duplicate 
cygwin1.dlls, remove them, and reboot.

You need to figure out why the postinstall scripts aren't running.  It's 
likely to be some permission issue as well.  As far as I can see, with the 
exception that your home directory isn't local, the '/etc/passwd' and 
'/etc/group' files should have been created fine.  Maybe your PDC isn't
available?  More than likely that's not it.  I'd concentrate on the 
permissions.

Oh, and not that this is a problem but since you mentioned that you did
a clean install as "just me", the output you sent was for "all users".  
The latter is really what you want anyway, if you ever think you'll 
run a Cygwin service.
