How to allow the users open servicedesk plus via their computers?

We installed the servicedesk+ on one of our servers.
It has been finalized and ready to be launched inside the company.
But how can make users and employees to open it through their computers and make requests?

I tried to publish (deploy) the servicedesk+ via the web server, but I encountered some problems.

any help or advice?
