Hi, Firstly, i am a networking newbie, so please go easy on me. Secondly, I am wondering if anyone can help me a problem i have regarding my computer and network? My setup is as follows: Two computers both using XP Home and up to SR2 level. Both have all of the latest updates from Windows Update. Both using the latest Zonealarm Free as a firewall. Connected by straight through cable to a D-Link DI-604 Router. Which in turn is connected to my ISP's Cable Modem. Both have an address of 192........ via the router. And the ISP address is 82....... via the modem. I have setup in the router software the 192. address for both computers. And i have also run the Windows XP Network Wizard again on both computers. But here are the questions.... 1. Neither computer can see the other one in Windows Explorer? 2. I have run two port scans on both computers and the results are as follows: PC Flank - Quick Test (IP Address) - port 139 is visible, and my browser settings can be seen. Gibson Corp - Shields Up - File Sharing Test - No port 139 showing open and no access to Netbios. Common ports test showing Closed - 113 Common ports test also showing Open - 1720 3. Can anyone explain the different results please? 4. And explain how i setup both computers to show folders? Many thanks in advance.
