whenever i do a netstat, the only entry which seems to be there every single time is:
"TCP computername:microsoft-ds computername:0 LISTENING"
what does this actually do?

I think that just indicates your computer (computername:microsoft-ds) is listening on tcp to another computer ( computername:0 ) = no active connection ??
what switches are you using? netstat -a should give you something like this that shows all active services and ports
Active Connections
Proto Local Address Foreign Address State

yeah, netstat -a was what i used
so that 'connection' isn't really an active connection at all...?

It's a listening port. If you have printer and file sharring enabled in XP, that's what it is. It listens for incoming requests. On a desktop, it can be a vulnerability for dos attack and other things.
"Microsoft-DS"....it's the service/protocol name for tcp\udp port 445 which as you may know is for File\Print Sharing.
