Netwrok Discovery

Hi All,

I am currently trying to use my vista home machine with media player
11 as a upnp server. I have done this in the past with the same
machine running xp with no problems.

Vista is uptodate as from yesterday with all including optional
updates.

The problem is when trying to turn on "Network Discovery" I need the
services dnscache, fdrespub, ssdpsrv, and upnphost all started.
dnscache, ssdpsrv, and upnphost are all running ok however I have a
problem with fdrespub.

When I try to start fdrespub I get an error message "Windows could not
start the Function Discovery Resource Publication service on Local
Computer. Error 0x80070001: Incorrect function."

The compter belongs to the WORKGROUP workgroup and has been
disconnected from any network. I have disabled my antivirus software
and windows firewall none of which help.

Any help would be greatly appreciated.

Thanks in advance
