How to Set Up Remote Access for Comcastby Stephen Lilley
If you have a Comcast Internet connection, you can set up your computer to be available for remote access sessions using a native Windows utility. Once set up, this allows you to connect to remote computers using your Internet connection. In addition, you can also allow other computers to connect to your machine remotely, which can be beneficial if you need to access your computer but aren't actually physically in front of it.
Right-click on "Computer."
Click "Advanced System Settings."
Click the "Remote" tab. Check the "Allow Remote Assistance" box to set up remote access on your Comcast Internet connection and Windows based computer.
