Re: Media Sharing no longer working with gigabit switch?

The switch is strictly a passive device, other than sending packets to
an appropriate port (this is controlled by the MAC address of each
network device on the switch)

Often, a switch will have an uplink port which is designed to link 2
switches or hubs together, and may have different properties to the
other 7 ports. Check in the switch's manual that you haven't connected
the PC to the uplink.

Other than that - it's worth testing the network properties of each PC
on the network. Did you (ever) use MAC Clone feature or re-assign the
MAC address of your network card(s) on one or more PC to be the same ?

You can view the MAC address on the PCs by going to Start -> Run, type
in

CMD

Press <enter> and in the command window, type

ipconfig /all

Press <enter> and write down the MAC address, which would be 6 pairs
of letters/numbers separated by colons ( : ) or dashes ( - ) for
example Physical Address. . . . . . . . . : 00-0B-FE-C1-23-A6

Compare those to other devices on the network or check in your
Router's web-based config pages to see if other devices match that MAC
address.

Thanks Vincent
But its a switch not a router the router/modem is a separate device on my
network and i havent changed any of the nat settings in there.
besides theres no nat between devices on the subnet only for outside stuff (
internet)
if the switch was blocking the routers upnp and for some strange reason it
affected the media sharing then i would be having probs with other things 2
like my web server ect. and other programs that need ports opened to work

Check if the switch allows UPnP, some block it by default

After replacing my ageing 100mbit network hub with a gigabit switch windows
media sharing in mediaplayer 11 no longer works in Vista or XP.
The new network switch is a "wiretek gigabit ethernet switch (8 ports)"
Everything else works ok the internet, network shares, web server, xboxlive
etc.
As soon as i put 2 devices( pc & xbox or pc & pc) back on the 100mb hub
media sharing works again.
