I recently upgraded from Windows Vista Ultimate to Windows 7 Ultimate. I have been having issues using media sharing ever since. I have both a PS3 and a D-Link media server on my network. Both of these detect my roommates computer running Windows XP. They have worked one time on my computer running windows 7 (after hours of trying), and I have not changed any programs since then. Currently my computer does not even recognize these devices. I have enabled media sharing, disabled windows firewall, disabled my antivirus, disabled my router's firewall and nothing has worked. I was running a static IP and I changed that to auto config and it still did not work. Please help!!!
