Ok I have a small home network with three computers, Vonage voip, and a 30/5mb cable connection. Heres how its setup
Dlink DI-634 wireless router
Vonage Voip box connected via cat 5 to the Dlink router
HP laptop w/ Dlink DWL-G650M wireless card(192.168.0.130)
Desktop1- 4200x2/2gig w/ on board Nforce4 nic via cat5(192.168.0.199)
Desktop2- 3800/2gig w/ on board Nforce4 nic via cat5(192.168.0.168)
Ok I have everything setup and each pc has a static IP i dont use dhcp. Everything was working perfectly until a week or two ago when I did a clean install of XP pro on Desktop1. Everything is still working except I cant send a file from Desktop1 to the Laptop, but if I do it the opposite from laptop to desktop1 it works fine. But the laptop wont even show up on Desktop1 network list and when I try to add the laptop folders it say it cannot be contacted. Everything else works fine. Any ideas what would cause this?? I have a feeling its a firewall problem but I cant figure it out. I have Zone Alarm pro on the Desktop and Comodo Firewall on the Laptop.
