You didn't mention if you got an error message, your operating system...
If you are an XP service Pack 2 user, or Windows 2000 for that matter try the following:
Open the DOS Command line and type:
telnet (hit enter key)
unset crlf (hit enter key)
o xxx.xxx.x.xxx (the xs are the IP address you are trying to access) (hit enter key)
the above line is the letter o not a zero
