Could this be a potential threat to systems? If the file Cusrmgr (part of the Win2K) resource kit allows you to write a batch program to change passwords. Could someone send you a zip file with a Bat or Exe file that places Cusrmgr on your system and a batch file in your startup folder to run cusrmgr.exe -u administrator -m \\YourSystemName -P Password which will change your Admin password to a PW of thier choice?

If this could not be a threat, what is stopping it from running? If it can be a threat. How would you counter this?
