Search for Web Services on Server

Not sure if I'm asking the correct question but on our company server I have access to a web service located at: http://site09.lab.mycompany.com:300/MainTripInfov1/TripInfov1. I want to search for other web services on that server. What application or process would I use? I tried Microsoft's Disco app but that retued nothing.

Is there such a tool that will search a server for web services?

Thanks
