How to Troubleshoot Application Connectivity Problems

Sometimes, you might be able to access the network with some applications but not others. For example, you might be able to download your e-mail but not access Web servers. Or, you might be able to view pages on a remote Web server but not connect to the computer with Remote Desktop.

Several issues might cause these symptoms (in rough order of likelihood):

  • The remote service is not running. For example, Remote Desktop might not be enabled on the remote computer.

  • The remote server has a firewall configured that is blocking that application's communications from your client computer.

  • A firewall between the client and server computer is blocking that application's communications.
