about why the computer is not connected remotely

At work, often to connect their own computer remotely, can be good the day before, suddenly not even on the, and then think of ways to solve.

1. Check if the remote connection is turned off on your computer. On my Computer-----> Properties-----> Remote for viewing.

2. See if your computer's firewall is off. Control Panel----> Security----> Firewall for viewing.

3. Check the computer service. Terminal Services to see if the service is prohibited, if prohibited, to open.

There are several ways to find out.

And it's mine that can be remotely to someone else's computer. Can also ping other people's computers. But the others will not ping me.

There's no solution.

Suddenly look at your IP address, cmd---->ipconfig view

Damn, your IP address has changed. I've always thought that IP addresses are not going to get. So the problem is solved.
