Web dispatcher - not working

Hello guys,

we have a problem concerning our web dispatcher.

Calling

[Link to site|http://pc7.phoron.com/]

we receive "The page cannot be displayed".

The SAP Management console tells us, that the responsible web dispatcher is not working. Trying to start it with sapwebdisp pf=... everything works fine (no error message or something like that). Looking back at the console the webdisp still appears green and neither the web page nor the web administration interface is reachable.

I don't really know why?!
