Updating an xbox 360
Once inside properties, scroll down the list until you see "internet protocol (TCP/IP)".
Double click and make sure both the IP and DNS server addresses are obtained automatically....
Click on "TVersity on (Computer Name)" (TVersity basically acts like another computer on the LAN)If TVersity installed and worked correctly, then this option should come up, otherwise, if it doesn't, then you have a problem with your Xbox finding TVersity.
Better yet, this is THE ONLY Microsoft program that is easy to install and use. It is imperative that you install version 11 because the previous versions haven't been written to help stream media to the Xbox 360.
Note: Do not miss this step as windows media player is a very important part of the process.
A message should come up detailing how to connect to a computer - press "yes, continue"It should now start searching for windows based pc's that are connected on the LAN.
Once it has finished searching it should come up with a list of computers on your network.
It uninstalled itself on my computer (How this happened i will never know) and I was trying to figure out why I kept getting connection error messages when trying to play non formats on my xbox.
