Brand new plesk box, added a domain

example.com

Then added the server's intended domain

server.com

but whenever a domain is entered that the server doesn't know what to do with it defaults to showing example.com not server.com. How do I make example.com the default? I have set the hostname to server.com and it didn't help.

Ok, for future reference.

1. Log in to Plesk.
2. Click on IP Addresses
3. Then click the number of domains on under hosting that correspond to the I.P. in question.
4. Select the radio button next to the domain you wish to make the default.
5. Click Set As Default

Done.
