MS Exchange server 5.5 cannot receive external mail 1

[legrand01]

Hallo,

can anyone help me fix my problem?
I had to change the way a company's exchange server 5.5 connects to its isp.
The connection was made thru a ISDN connection and now the connecting has to go thru a ADSL connection.
I dissabled the dailin connection and can send email from the the server to external addresses but unable to receive external mails.
Maybe someone knows and can point me the right direction to look for the solution. All the help is welcome.
(even a thread is welcome).
Thanks in advanced.

Do you have a static IP? Find out where is your domin's authoritative DNS and update your MX record to point to your Exchange server's new IP address.

Thanks NOktar for your reply.
I will check this when I'm in Office later.

The NT4 server has a static IP and my workstations are DHCP configured
(the adsl modem/router is the DHCP server).
I have disconnected the available connection (Internet Mail Service Properties/Dial-up conections) and on the connections tab I have unchecked the dial using option.

When you are using a ADSL connection, how do you make the connection, when you are not dialing-in?
