Non-IPv4 telnet Connections Are Not Secured on Windows Server 2008

On Windows Server 2008, CA Access Control cannot secure a telnet connection unless it uses IPv4.

To protect a localhost telnet connection–telnet from the localhost to the localhost–on Windows Server 2008, modify the /etc/HOSTS file as follows:

127.0.0.1        localhost
#       ::1                 localhost
127.0.0.1        <your server name without domain suffix> 

If your computer is on an IPv6 domain, add the following line:

127.0.0.1    <your server name with domain suffix>
