Set up Knoppix on peer to peer network with Windows XP

I have a peer to peer network currently running Windows 98 and Windows XP. I have my internet connection (DSL) on the XP machine. I have replaced the Windows 98 with one of the latest versions on Knoppix. I would like the Knoppix machine to run a network printer and access the internet for kids to download music etc. My problem is networking the two. I can't see the Knoppix machine from the XP machine nor can I see the XP machine from the knoppix machine. When I try using the network wizard on Knoppix I get a message saying something about SA not running....

Sorry that error was "SU returned with an error".
