Hello Everyone...

I just got linux a couple of days ago, and I'm having fun relearning everything...
Anyways, here's my problem:

I'm trying to get access to my home network - my father uses winXP, and my sister uses Win2000.
When I configure LISa in the KDE gui, it says everything is working but to make sure LISa is starting up with a boot script. (I've checked this, and LISa is there). When I open up Konqueror and go to lan:/ , it tells me that LISa isn't running and I need to enable it. When I boot my laptop it tells me that eth0 (my network card) does not seem to be present, so it delays initialization. However, once the computer finishes booting and I view the card, it says that it's working fine. I also am running the internet through the network (it's shared from my father's computer), so dhcp works.

Can anyone give me any pointers on how to continue from here?
