Death of NT4

[Mobo]

NT Server 4 doomsday has arrived. On Jan. 1, Microsoft's no-fee support and non-security hot fixes disappear. So what are you going to do now?

Well, you'll need to do something. New security holes continue to be found in NT on a regular basis.

For example, if you replicate data between WINS (Windows Internet Name Service) servers to determine the NetBIOS name server for IP addresses associated with particular network computers, an attacker can take over your NT WINS server.

Microsoft has several work-around solutions to this problem. Some of them, such as blocking TCP port 42 and UDP port 42 at the firewall and simply removing WINS from your servers, defeat the entire purpose of using WINS over an Internet in the first place. The more sensible approach is to use the VPN (virtual private network) protocol, IPSec (IP Security), to filter WINS traffic.
