Righty oh’ then all setup with media center (I’ve gone a bit further and knocked something up for media server on server 2003 but more of that in a later post). You may however have noticed that the OneCare firewall does not play well (or if you could not connect at all this is probably why).

Here’s whats needed to get it all working…..

1. Open up OneCare and head for the view or change settings option
2. Select firewall then advanced
3. Click the add button and add these 3 applications (usually found in \windows\ehome) MCXNetTw.exe, MCRMgr.exe and Ehexthost.exe
4. Click the ports and protocols tab
5. Add the following items (all local subnet and inbound only)
   TCP 5555 and UDP 7777 are required for the ehshell.exe
   UDP 3776 is required for Mcrdsvc.exe
   TCP 3390 and UDP 1900 are required for Svchost.exe
6. You should therefore now have 3 trusted applications and 5 listening ports allowed in your firewall

You should (with a little luck) now be able to connect your 360 up to the media center and still have the firewall enabled.
