I have a situation where I need to change the usernames for over 200 users. We are using NT4 TSE. I know of being able to create users and change passwords from the command line for a list of users with the following For /f "tokens=1,2" %i in (c:\<userlist>) do net user %i %j /add /domain Is there a way to use the net user command to change usernames? The reason is this All our usernames start off with a 4 letter code that identifies the company they are in, and one of our customers has changed the name of their company, as a result I need to change the 4 letter code at the beginning of the username. But with over 200 users in this company alone it would be tedious to say the least. Any ideas?
