Hello,
Today I will show you how to disable telnet server on your Windows machine, as many hosters have issues with crashing TheForgottenServer when someone spams connection attempts. But first, I'll explain a little why you should do that...
Telnet isn't used nowadays as before due to lack of security. It has been replaced almost everywhere by OpenSSH, which you probably know or at least heard of. Why that happened? Because Telnet sends clear text passwords and usernames through logins. That's why should be disabled on all servers. Some hosting providers are not disabling telnet by default, so you should ensure that it has been turned off as it's a great security risk to your servers. If you are using it, consider replacing.
So, you still want it enabled? Follow these steps if you decided to disable.
1. Click on "Start" button, then go to "Control Panel".
2a. (Windows Vista, Seven and Server 2008 users) Click the "System" icon and then "Administrator Tools";
2b. (Any other) Click the "Performance and Maintenance" icon. If the "Performance and Maintenance" icon is not present, the "Control Panel" might be set to classic view. If so, locate and click the "Administrative Tools" icon. Clicking either icon opens the "Administrative Tools" window.
3. Click on "Services" applet (services.msc if you prefer to use Run command or Start Search).
4. Locate the "Telnet" service, right-click on it and select "Properties".
5. In the "Startup Type" drop down menu, select "Disabled".
6. Click the "Apply" button, then click the "OK" button to complete the process.
If you followed point "2a" (VISTA, SEVEN or 2008), you may also want to uninstall it...
1. Go back to the "Control Panel" and click on "Programs".
2. Under the "Programs and Features" section, click "Turn Windows features on or off". If "User Account Control" permission confirmation request warning pops up, click on "Continue". If you are prompted for an administrator password, type the password.
3. In the "Windows Features" dialog box, deselect (remove the tick as on image below) the Telnet Server check box.
At the end I want to note, that it would be great if you would even disable port 23 on your firewall (Windows or any other you use), which is the port used by Telnet server and client.
Enjoy.
