Okay, I am a pretty technical user, and I am really struggling with this issue, and I wasn't 100% sure which section to post this in. I used to share videos over my network with multiple xboxs and a ps3. I recently installed Norton Internet Security on my system, and after doing so, I was not able to stream videos anymore. I tried changing firewall settings, and permissions and such, but could not get it to work, so I uninstalled NIS from my system. After doing so, the Windows 7 firewall service will not start. If i look at the event log, it gives me Event ID 7024 : The Windows Firewall service terminated with service-specific error Access is denied.. I have run the norton removal tool, and this has not fixed the problem.
