Select WorkgroupMail Administrator from the WorkgroupMail menu item in the start menu.
You are presented with a login dialog box. The username must always be Administrator. Initially there is no password, so you can log into the WorkgroupMail Administrator program by pressing the Login button.
If you wish to change the password (highly recommended) then do so by pressing the Change Password button. The Change Password dialog box is displayed. Enter your old password into the Old Password field (leave blank in this case) and then enter a new password into the New Password and Verify fields.
When you press OK, the Login dialog box is displayed once again with the new password already entered into the Password field. Press Login to log into the WorkgroupMail Administrator.
