Windows7 how to open the remote desktop

1, desktop-computer, right-click properties, point to the remote settings on the left, it comes out like the remote desktop interface in the XP system, directly click on the computer that allows any version of the remote desktop to click on the application, prompt Because the firewall is closed, you can't open the remote desktop. No? Go to the control panel and see, the firewall is not open, not only has not been opened, but also disabled! Shenma situation!!! Find instructions in the installed system disk: One of them is "close the firewall service;", I am going to go to the control panel - management tools - services, find the windows firewall, md is really disabled, changed to automatic - start, back to the remote desktop settings This is fine, but there is an exclamation mark above: Windows Firewall exception must be enabled for the remote desktop, which is a link, click and appear:
When Windows Firewall is enabled, use Remote Desktop
because of Windows Firewall restrictions Communication between the computer and the Internet, you may need to change the settings for the remote desktop connection to Make it work.
Click to open the Windows Firewall.
In the left pane, click “Allow programs or features through Windows Firewall”.
Click “Change Settings”. Administrator rights are required. If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.
Under "Allowed programs and features", check the box next to "Remote Desktop" and use the checkboxes in the column to select the type of network location you want to allow communication with.
Click “OK”.
Note
If the "Change Settings" button is not available, you may not have permission to change certain settings managed by your system administrator.
Okay, oh go to the firewall - allow the program or function to look through the Windows Firewall, the result is "Change settings" button is gray, not available!!! I am really defeated!!!
This can be done? Online search, a lot of said to upgrade to administrator privileges, but it is already an administrator, and then think about the group strategy to see it, is the group made any restrictions?
2, computer right button, group policy (this is the system integration of this version, how to enter the group policy to be checked), enter the computer configuration - management template - network - network connection - windows firewall - standard configuration file - windows firewall: allow Inbound remote desktop exception, double click, default is not configured, select is enabled, enter * in the following IP address (if you want to fix ip, follow the instructions), confirm, test success
