wildred:

I built a Perl script to do something like what you are looking for, although it scans IP address ranges rather than machine names but you could pipe in a list of machine names.

My need was to check the local administrator password on every PC. It logged the result to a file (re.; successfull or not).

I'm sure it could be modified to just try to either map a drive to one of the admin shares or simply try to get a directory of it. Failure could be a result of 1 of 2 things: 1) admin shares are disabled, or 2) the account you are running the Perl script as (locally logged in on box you are running it from) does not have admin rights to the PC.

If interested let me know and I'll send you the Perl script...after I clean it up a bit.
