Telnet Client in Windows Server 2008 + R2

One of the more inexplicable omissions in Windows Server 2008 and R2 is a telnet client - maybe it saved 8kb or something, maybe it was a security thing but it was definitely annoying.  On running telnet on a 2008 server by default you get the worrying message "'telnet' is not recognized as an internal or external command".

The command to restore this basic functionality is:

servermanagercmd -install Telnet-Client

It works in R2 too though it does whinge that you should be using Powershell.  Yes, whatever, just get on with it.

  1. Thank you for this. Was needing to test connectivity to Exchange server. Found instructions telling me to see if I could connect via Telnet. When I tried that I got the 'telnet' is not recognized message. Googled that and found this.

    Yay!
