lmhosts file in c:\windows

[don_mccall at hp.com]

A couple of thoughts - 
1. what is your subnet mask on the windows box with the lmhosts file?  By 
default for a 192 network it would be 255.255.255.0, which would mean that 
haarlem and zaandam are on different subnets, and you would need a route entry 
to get to whichever one is not on your 'local' subnet.
2. can you 'ping' 192.168.4.20 from your command prompt?
3. What is the ip address of your windows machine? 192.168.7.something?
Hope this helps,
Don
