For some reason only known to Microsoft, telnet isn’t installed by default in Windows Vista, although its easy enough to install, but a pain when working remotely and you get kicked off by UAC whilst working via VNC, then you get a DOA connection :D
Anywho, here is how to do it:
1. Click your Start button and navigate to Control Panel.
2. From Control Panel double click Programs and Features.
3. Click “Turn Windows features on or off.”
4. Choose Telnet Client from the list.
5. Click the OK button.
6. A dialogue box will appear to asking you to confirm the installation.
Once this is installed you will now be able to issue the telnet command from the cmd/command prompt. Most useful and used often to test for listening services and open ports.
Here is something to ponder, do Windows users claim that Windows Vistas effects are a waste of time because they have already been done, and done better on other systems such as Mac OSX and Linux?
If Windows Vista was the ONLY OS that had those special effects, I bet the Windows user camp would be shouting from the rooftops about them.
