I have tried to do the File&Printer Sharing.  I have Windows Vista-64Bit.  I can use the Printer from 9100 Dimension-XP Home.  So I guess it worked (filesharing).  I also see my Laptop in the Network.  It is a Toshiba Laptop.  I can't get that to work.  Something to do with the Driver.

This is what is happening now.  When I turn on Studio XPS 435MT (hooked up to a Router&Modem), I get a red X where the two computers are (task bar), but I am connected to the Internet because the Laptop and Dimension 9100 is connected.  I can go online using Studio.  The only thing I can't do is get Windows Mail and I can't get to Network.  But after 20 minutes the red X disappears and things work just fine.

Does anyone know why this happening. 

When I first got Studio after Dell helped me install new Printer Dell V505 they had to do several trys for the right Driver.  Could it have something to do with the Driver?

Please help me!

Thanks
