Teamviewer

I recently started using TeamViewer to accomplish some of my remote administration tasks. I have been a loyal fan of LogMeIn for several years now. I love their service, but there is two features that I extremely liked about TeamViewer that are not offered as an option to LogMeIn Free subscribers. These two features are the desktop client and the QuickSupport application. The desktop application allows you to quickly open up a remote access window to your machines without having to visit TeamViewer’s site (similar to LogMeIn’s Network Console).  QuickSupport allows an outside user to quickly launch the application, without the need of an install, and provide you remote access by giving your their generated user id and password.

So what’s the problem? Well, if you’ve ever used TeamViewer, and try to do a little development on a local wamp/xampp server, then you will find that you can no longer access your local server because TeamViewer has taken over Port 80. Here’s how to fix it.

After talking with TeamViewer tech support, I received an email giving me instructions on how to disable TeamViewer from listening on Port 80.  Instructions are as follows:

1. Open port 5938 (TCP) on your firewall.
2. Change the following registry keys.

• [HKEY_LOCAL_MACHINE\SOFTWARE\
  TeamViewer\Version4]  Key  ’GatewayAllowed’ set to 0
• [HKEY_LOCAL_MACHINE\SOFTWARE\TeamViewer\Version4]  Key  ’ListenHttp’ set to 0

After you make these changes, you should no longer have TeamViewer listening in on port 80, killing  your local web server.

Hope this helps someone else.
