help lan kanotix/win xp

I have a netgear router with 4 ethernet ports. I have 2 win xp boxes
working together with LAN. I have added
a Linux box Debian derived KANOTIX.
When i go to my router adress i see my 3 machines from win
xp but i cannot
see my windows machines from Linux.
What is the usual proceedings in Debian derived OS to put the Linux
box into the windows LAN ???
thank you for helping
