Quickly add large numbers of users to a computer or server using addusers.exe

addusers.exe is a great tool that is included in Windows 2000 Resource Kit and is described by Microsoft as “32-bit administrative utility that uses a comma-delimited text file to create, modify, and delete user accounts”. The main benefit is using something like Excel or notepad to create a list of users, passwords and other details and then instantly generating their user accounts. We had to do this recently for almost 100 user accounts and it took seconds once we had written the text file. Although this isn’t officially supported on Windows 2003 or later, it still worked for us.

You can download addusers.exe direct from Microsoft’s FTP server or from Petri.il.

The command we used to import a list of users contained in “listofusers.txt” to our server “servername” using addusers.exe was:

addusers /C C:listofusers.txt \servername /P:LE

Where the text file listofusers.txt looked something like:

username1,User Fullname,p4ssword,email@somesite.com
username2,User2 Fullname,p4ssword2,email2@somesite.com

You can do a lot more with addusers.exe but this is a very handy and quick way of managing the creation of large numbers of users.
