Configuration to access Web Service running on Host System from VM

Hi,

on my Host System (Windows 7) I'm running a local Web Service that I'd like to access from within a Virtual Machine (Windows XP), that is running locally in VMware Player 5.0.0.

From within the VM, I'm able to ping my Host System and access shared folders. On my Host System, I can see the WSDL-File if I type its URL into a browser (e.g., http://HostName:8080/WebService?wsdl). However, typing the same URL to a browser on the VM does not return anything.

Please tell me, what else needs to be configured, in order to access my host's web service from the vm!

Thanks

D
