The result is that the certificate is shared by all users on the client machine (if there is only one user this should not be a problem of course). Fixed IP addresses are not required for clients which use certificates. Alternatively, you could make a VPN connection from the client itself, bypasssing Windows 2000 Server. have a peek here Art Bunch posted Jul 11, 2016 Do i need windows 8 security...
