I just recently bought a Dynex DX-ESW5 5 Port Standard Ethernet Switch, to setup a small LAN at my home. However, I am having issues with all of my devices save one not being able to connect. My main Desktop PC can connect to the net, but my Laptop (Also, my Laptop does not appear on my LAN in My Network Places) and PS2 cannot. I have hooked up everything properly as far as I can tell, and I configured my PS2 and LAptop to have static IP addresses while my main PC is set to resolve it's IP automatically using DHCP (I'm using Comcast Cable for my ISP, if that's of any relevance). I have ran the Windows Network Setup Wizard on both my Laptop and Desktop, to no avail.

My Ethernet Switch does not come with a built-in firewall, so I shouldn't need to forward my ports or create a DMZ.

Any suggestions or help with this issue is appreciated.

Edit: I'm using Windows XP Pro (32-bit) on both PC's.
