How to replace Telnet with PuTTY in Internet Explorer 7

A few customers have asked us why the Telnet link in Scrutinizer doesn’t seem to work in Microsoft’s Internet Explorer 7.  According to the Release Notes for Internet Explorer 7,  the Telnet protocol handler is no longer supported in Internet Explorer 7, preventing any links using Telnet to work.

The good news is that there are modifications we can make to either enable Telnet, or use an SSH client like PuTTY in place of Telnet.

Personally I’m a fan of replacing Telnet with the PuTTY SSH Client.  Click on How to replace Telnet with PuTTY in IE7  to view a PDF file with step-by-step instructions and screenshots.

If you prefer Telnet, The University of California Berkley published a nice article on How to enable Telnet for IE7 and Firefox for use with their internal website, but once you have it enabled, it works for any website.  They use a script to make modifications to registry keys that re-enables Telnet.

These instructions are for the client machines and not for the server itself, unless you plan on using the browser on the server.

Have fun!
