Window Media Player Network Sharing Service - Media Sharing

Attempting to get media sharing started on windows media player 11 was
a massive task, although it can be straight forward if you have a pc
straight out of the box or are familiar with the set up of your pc for
some it is not. Every time I switched media sharing on it would not
show my ps3 even though I had media serving enabled on my ps3.

I checked my firewall and found it was blocking Window Media Player
Network Sharing Service all 6 ports were greyed out, basically, my
laptop was part of a domain a long time ago and had a goup policy set
up to deny this service. So after removing my laptop from this
domain, which removes it from the group policy I then had the ability
to use the service, however, in the list of services I discovered that
Window Media Player Network Sharing Service would not start. I would
receive the error: error 1008:an attempt was made to reference a token
that does not exist.

This was becoming really tiresome, and there wasn't much info on
google about how to resolve this, so I uninstalled WMP 11 which rolls
it back to 10, started up 10 to make sure it was properly configured,
then upgraded back to 11 and all of a sudden Window Media Player
Network Sharing Service starts automatically as was intended and when
I turned media sharing on my ps3 is now visible!!!

Success, finally!!

Hope this helps anyone with similar problems....
