Note: 
Network discovery requires that the DNS Client, Function Discovery Resource 
Publication, SSDP Discovery, and UPnP Device Host services are started, that 
network discovery is allowed to communicate through Windows Firewall, and that 
other firewalls are not interfering with network discovery. 
To check that the UPnP Device Host services are running: 
1.  Click   (Start) and type in the Search programs and files field services.msc and then 
select services.msc from the displayed Programs. The Services manager dialog box appears. 
2.  In the Services manager dialog box, scroll down the list to UPnP Device Host and verify that 
it shows the status Started. If Started is not displayed, right-click and select Start from the 
shortcut menu.
