Go to Start, type Windows Firewall and open the utility. Click Allow a program through Windows Firewall and check the box next to the application. If you can't see the software in the Allowed programs and features window, use the Allow another program button to navigate to the installation folder. After that, open Windows Firewall with Advanced Security tool, select the Inbound Rules from the left and press the New Rule option below the Action tab. Select Port as a Rule Type, click Next, check the Specific local ports box and enter 5222 value in the provided field. Click again Next and follow the instructions. Also, make sure that your antivirus doesn't block the connection. If the problem is not solved, I suggest you download and install Google Talk. It is the latest version of the utility.
