Introduction

2- Create FTP users

You need to create users in Windows in order to be able to use FTP services.
You can use either local or domain users.
In this case, I will create some local users.
The only thing that changes if you use domain users is, when you log in to FTP, you must use the domain/account format.

4. Click Users
5. In the center pane, right-click a blank area and then select New User…

7. Create as many usernames you need here.

Optionally, you can create a group that contains all the FTP users in the Groups folder and add the users you created above.

You need to configure some global settings for your IIS server before creating your FTP site.
It is very easy, follow the steps below:
