| 208096 | 2004-01-17 20:37:00 | We've installed Sygate firewalls on our system (3 Win XP m/c's networked thru a D-Link router to Jetstream) and I've been looking at the traffic logs. There's a program called ntoskrnl.exe that runs every few minutes. Does anyone know what it does and if it's needed at all? When we first set up the firewalls, we blocked everything that we didn't recognise, but that stopped us communicating between m/c's, so we had to back-off and allow things like dne2000.sys, ndisuio.sys, etc. God knows what they do, or why we need them. Is there a web resource somewhere that explains which programs are needed and which are not? We've blocked Messenger with no ill effects so far, but what does it want to do? And why does it want to talk to the outside world every few minutes? What is it telling them? |

What is it telling them? This was discussed in a recent thread (pressf1.pcworld.co.nz). Rather than just blocking Windows Messenger, you can disabled it completely. >When we first set up the firewalls, we blocked everything that we didn't recognise, but that stopped us communicating between m/c's, so we had to back-off and allow things like dne2000.sys, ndisuio.sys, etc. God knows what they do, or why we need them. Is there a web resource somewhere that explains which programs are needed and which are not? Google is wonderful :D. Search on the items for more information and see if that explains it for you. If not, post back for further advice on the item(s). :) |

Right, so why is the "kernel of the operating system" hitting my firewall every few minutes trying to send something out? And what's with NT? I'm running XP Home. I've had it blocked now for several days and nothing has gone wrong - so far. How can I disable it? |

| 208101 | 2004-01-18 09:34:00 | Don't know why the kernel is hitting the firewall. The NT bit is just showing XP's origins - from the NT stream of Windows not the 9x stream. MS haven't bothered to change the name of the kernel. |
