Windows 7 : Using Dynamic DNS to Access Your Network & Configuring a Network Computer for Remote Administration

Using Dynamic DNS to Access Your Network

If you want to use Remote Desktop via the Internet regularly, constantly monitoring your dynamic IP address can be a pain, particularly if you forget to check it before heading out of the office. A useful solution is to sign up with a dynamic domain name system DNS (DDNS) service, which supplies you with a static domain name. The service also installs a program on your computer that monitors your IP address and updates the service’s DDNS servers to point your domain name to your IP address. Here are some DDNS services to check out:

DynDNS (www.dyndns.org)

TZO (www.tzo.com)

No-IP.com (www.no-ip.com)

D-Link (www.dlinkddns.com)

However, you may not want to rely on a program to keep your network external IP address and your domain name synchronized. For example, you may want to turn off the computer when you’re away from home or the office. In that case, most routers offer a DDNS feature that will handle this for you. You specify your DDNS provider, your domain name, and your logon data, and the router does the rest. Figure 1 shows an example.

Figure 1. In your router’s setup pages, configure dynamic DNS.


Configuring a Network Computer for Remote Administration

You can use Windows’ remote administration tools to work with remote computers from the comfort of your own PC. Remote administration tools mostly use the Remote Procedure Call (RPC) protocol to communicate with the remote computer. RPC enables a local computer to run a program on a remote computer. For this to happen successfully, you must configure an exception in the remote computer’s firewall that allows RPC traffic.

Here are the steps to follow:

1.
In Windows 7, select Start and type command.

2.
Right-click Command Prompt, and then click Run as Administrator. The User Account Control dialog box appears.

3.
Enter your UAC credentials to open the Administrator command line.

4.
At the prompt, enter the following command:

netsh firewall set service type=remoteadmin mode=enable
