I have a network that I assign IP's to all PC's. There are numerous computers in the network but I mainly use three of them. On the main machine I can access my laptop. On my laptop I can access the main Pc. The problem is my spare pc. i cannot access the spare pc from the main or the laptop. I am trying to be able to view the drives and copy files, etc. I can, however, access the internet from the spare as well as ping the main and laptop. Also the main and laptop can ping the spare. BTW laptop is wireless but everything else is wired. All are on the same Domain name. ANy ideas what I am doing wrong? All pc's running XP. All have windows firewalls off.
