Practice
There is a Windows XP SP2 workstation in a Windows Server 2003 domain. It is necessary to allow printing to a network printer from DOS applications.
From under the user account we run

The command net use lpt2: with the same parameters runs without any problem. If you log in with the domain administrator account, there is also no problem. The domain user account is included in the computer's local "Power Users" group, and there is no local user account. If the domain user is added to the local "Administrators" group, the command runs normally.
The reason is that the user does not have permission to use the LPT1 port, while the administrator does. The password prompt in this case is not for connecting the printer, but for disconnecting LPT1 from its binding to the physical port.
