Guys,
Ok, I have re-installed the machine, formatted and fresh.
Let me give some background anyway >
* The machine was powered up one morning after a previous day of no problems what so ever, it bluescreened and was turned off, then powered back on, it got to the windows logon prompt and when I keyed in my user details it said "Unable to log you on because the netlogon service is not running on this machine" and that was it!
So I restarted again, pressed F8 and used "Use last known good configuration", it booted up once more, the disk was being used 100% for around 15 mins, I then tried to log in, keyed my user name / password and it say in the logon prompt for about 35 mins, so I shut it down.
I booted it back up and I was faced with a new problem, bluescreen with "Inaccessable_Boot_Device", so I turned the pc off once more.
Stuck the Win2k pro cd in the drive, attempted to do a fast repair with all options, and I couldn't find the Windows installation, the recovery console worked, but I did not continue with this for lack of knowledge.
Anyway, the machine has been re-installed and is working healthy again! but I have taken a ghost image just in case!

Wulluf - I should have tried that instead of dumping the whole thing, I never knew the Win2k installs could do that! but you learn something every day!
No software or hardware was changed, but the bluescreen above did occur.

Swimpy - I could not log in whatsoever.
Yes, the cable is plugged in and a light is on the hub, it was not logging onto a domain of any kind so their shouldn't have been a problem here.
Thanks for all your help Gentlemen, I appreciate your time and consideration in helping me here, it got me much further than I was. Have some free stars to keep!

;-)
Kind Regards,
Luke
