I'm trying to network my new computer with Windows XP Media on it and it won't take. I have Five Computers; all four running through router using Windows XP Home Edition and no problem sharing files and printers. However when I get to my new computer with the Windows XP Media Center OS I cannot go out from that computer to find the other computers or printers. I can go to any other computer in the network and read the files on the new computer but not visa versa. What gives? What should I Try?
