Hi bb34nne,
You need CDA (Customer Database Administrator) to do this.
In List Of Customers you Add a Customer.
Then rightclick on this Customer and click on Add Site.
Fill in the needed data and click on Next.
Fill in UserName and Password, click in Channels on New and fill in Channel Name (your pc) and Connection Type(LAN, modem or Serial). When you choose LAN here LAN Selection appears. Here you can fill in the IPAdress of your MD and click the button to complete the procedure.
Now, when you startup MDDT you'll see in List of Customers the Customer you added and there you find the site you added. Click on that site and it will connect to your MD.
I hope this helps.
Greetings.
