I had this problem before but it seemed to corrent itself. Not his time.

I have a small wired home network (2 laptops and 1 desktop) using an Inexq router and Windows XP Home SP2, Norton AV with XP firewall. Network ran perfect for months with ability to see and change shared files at will. The other day, one laptop decided to crap out. No network. Server service is working, files set to share but nothing shows up when wizard applied. Laptop doesn't appear on other machines either.
