How to enable Telnet Server and Telnet Client in Windows?



How to enable Telnet Client and Server ? Before going to that let’s talk a bit about what is TELNET and why we need it. If you are configuring DATABASE MAIL then you need to test the connectivity to the MAIL SERVER you use in the Database mail settings. To TEST the CONNECTIVITY to any mail server we use command prompt keyword TELNET. This  service needs to be enabled to make use of the same. If the TELNET is not enabled the you will get the following error.

“TELNET is not recognized as an internal or external command”

Now lets see the steps involved to enable the TELNET Client and Server.

  • Go to control panel
  • Select Programs (in windows 7) and Programs and features in earlier versions as shown below.

  • Select TURN WINDOWS FEATURES ON OR OFF option as shown below.

  • A popup will open and check the options Telnet Client and Telnet Server and click OK. This will take few minutes to enable the same.

  • Now go back and execute the same command to test the MAIL SERVER in command prompt. You can see the TELNET is recognized. Now you can provide correct mail server to test the connectivity.

Hope it helps you .. 🙂
