After entering the URL into your browser and pressing enter, you will see the RemotelyAnywhere Login screen.

RemotelyAnywhere will access the user database to authenticate the user. Initially, you will need to log on as someone who is a member of the Administrators group. You can later change this default behavior by granting NT users or NT groups access to RemotelyAnywhere under Security > Access Control.

By clicking NTLM you can use your current Windows login credentials to verify your identity on the Host. This option is only available on local networks when accessing a Windows XP computer. It will use your current credentials (those you entered at the NT logon prompt on the computer running your browser) to identify you to the Host.
