PsGetSid

PsGetsid is a command-line utility that can help you view the corresponding computer name of a Security Identifier Definition (in short, SID). Part of Sysinternals' PsTools, this lightweight application can also retrieve your computer's SID number.

Get the SID of computers and user accounts

PsGetsid works with both domain and local user accounts, translating the SID number to the display name and viceversa. It exclusively runs in the command prompt, mainly addressing experienced users that are already familiar with the console and the way it is used.
Launching the application without any additional command will reveal the SID number allocated to your computer. If you want to see all the available commands, you must use the 'help' option.

Query remote and local computers

Provided you have the proper rights, PsGetsid can access a remote computer and retrieve its SID number and name. It comes with options to specify the username and the password used for logging in to the target machine. Entering a password is not mandatory, but in this case you are prompted to type it in later.
The application can also be used for reporting the user account for the specified SID number, rather than the computer's name. Moreover, it can perform a command on multiple computers or even all the workstations in the current domain, provided a wildcard is specified. You can either enter the name of the computers one by one or pass the path of a text file containing this information as an argument to the command.

Translate SID numbers into computer names and viceversa

PsGetsid can easily display the SID number for the local or a remote computer, as well as a user's account. To query a remote computer, administrative privileges are required, which must be specified in the typed in command.
