I'm trying to enable media sharing from WMP11. The media sharing
dialog
presents itself, whereby I select to "Share my media", hit OK - and
then no
reponse and I return to the same dialog as if I had not done anything.

I've checked the Event Viewer and it records a system error (Event ID:
7001)
- "The WMP Network Sharing Service service depends on the UPNP Device
Host
service which failed to start because of the error: %%0"

I've tried to manually start the UPNPhost service but it starts and
then
stops immediately.

Any help would be appreciated.
