I have to add my .02 here too - I'm not sure if the fact I know how DNS works colors my opinion, but I found this software to be wonderful. It's easy to use, does a splendid job of organizing tickets and tech, and was super-simple to install. I highly recommend it.
As far as the problems mentioned in another review; The install is package based. You double click a package and install the app just like any other when using the default database. If you have an existing database solution you want to leverage, you can use MySQL or something else. But unless you have an existing database or some specific reason, going with the default database is recommended. You can also easily change the port ( to the web default even; 80 ), and of course if you have any kind of DNS operating on your network this machine can be given a more easily accessible name.
And the support is fantastic; I called to ask a few questions and an hour later not only had my issues addressed but was also given a complete overview of the product and it's capabilities. These guys use the product themselves everyday! If you need some kind of helpdesk solution, no matter what platform you are running I highly recommend Web Help Desk.
