Renaming the Site address to Service Desk Plus?

Dear All
 
I hope someone can help me with this question, we currently have service desk v8 installed and would like to rename the current site's address from \\servername:8080 to someting more useful to end users such as \\servicedesk  - could somebody advise the easiest way to carry out this task?
 
cheers
