If you’re trying to test connectivity between servers on a specific port and you go to use TelNet and receive a nasty little message that tells you that “telnet is not recognized as an internal or external command, operable program or batch file.” run the following from your administrative command prompt
1 |
pkgmgr /iu:"TelnetClient" |
Close the command prompt for good measure and try to use Telnet once more
Then if you want to uninstall Telnet, just replace /iu: with /uu:

pkgmgr /uu:"TelnetClient" |
