The main advantage of using this is remote access on the network.

The inherent problem in answering this question is that Windows XP does not have a Telnet server included, so there would typically be no purpose in even attempting it. You would need to install a third-party Telnet server (of which there are several) on Windows XP first. After the Telnet server is running, just open a command prompt in Windows Vista and enter:telnet substituting, of course, the correct IP address and leaving out the brackets.
Telnet operates over TCP Port 23.
Because the telnet session is in clear text and programs can capture the passwords to log in to telnet sessions.
Windows: Open start menu, click "Run", type in "telnet" Linux: Open a Terminal window, type in "telnet"
