Unable to Connect to the Skype Network: Error 1101, 1102, or 1103

When the Skype application is unable to connect to the network, you will get error code 1101, 1102, or 1103, or the Skype application will continue to display "Connecting" in an ongoing attempt to reach the Internet.

This can happen for several reasons. At home, this typically happens as the result of how a software firewall or router is configured. At work or school, this typically happens as the result of how a hardware firewall or proxy server is configured. In both cases, it can happen as the result of how Microsoft Windows' Data Execution Prevention (DEP) is configured.

Trouble Connecting at Home

If you're having trouble connecting to the Skype network at home, the first thing to do is determine whether you have a live connection to the Internet. To do this, try checking your e-mail or pointing your Web browser to a Web page that you know changes frequently, such as Yahoo! or Google News.

If you have a connection to the Internet, next determine whether a software firewall is interfering with Skype's ability to connect. To do this, quit Skype, and reconfigure the software firewall as described in Appendix C.

If the problem doesn't appear to be a software firewall, and you are using a router or wireless access point, try restarting or rebooting your router. To reboot a router, follow these steps:

1.	Shut down any computer that is connected directly to the router with a wire.
2.	On your router, turn the power off or unplug it.
3.	Turn off your broadband (cable or DSL) modem, and wait 30 seconds.
4.	Turn on your broadband (cable or DSL) modem, and wait 2 minutes.
5.	Turn on the router.
6.	Restart the computer.

If you don't have a router, and you are still having problems, log on to http://forum.skype.com, and search for assistance. You can also check the online troubleshooter and user guides at http://support.skype.com.

As a last resort, you can submit a support request outlining the steps you've taken to solve the problem thus far. Be sure to provide a detailed description of your computer configuration, including hardware, operating system, and a list of the programs you are running while trying to use Skype.

Trouble Connecting at Work or School

If you're having trouble connecting to the Skype network from work or school, contact your system administrator to get help or find out whether Skype is allowed on the network. Some system administrators block peer-to-peer (P2P) programs like Skype to prevent file sharing. If your system administrator has questions about proper network configuration for Skype, refer him to the configuration instructions in Appendix C.

Microsoft Windows DEP

Microsoft Windows XP (Service Pack 2) and Windows 2000 Server have a configuration option that prevents unauthorized application programs from running. If DEP is enabled and is not configured to allow Skype to run, Skype will crash if you try to start the application.

To reconfigure DEP to allow Skype to run, follow these steps:

1.	Choose Start > Control Panel > System.
2.	In the System Properties window, navigate to the Advanced tab.
3.	In the Performance section, click the Settings button. This will open the Performance Options dialog box.
4.	Navigate to the Data Execution Prevention tab, and click the radio button labeled Turn on DEP for All Programs and Services Except Those I Select.
5.	Click the Add button.
6.	Add Skype.exe to the list of the programs that DEP will allow.
7.	Click Apply and then click OK.
