by accessing the number through ipconfig/all from a command prompt.
Firewalls are one of the main reasons people fail to network their machines. For this reason I would turn them off until a viable network has been established. Then I would :
1) check the workgroup names
2) check the IP/subnet ranges for each machine
3) search for each computer by IP and then by name
I just installed a simple wireless network using:
1) Netgear RangeMax router (WPN824) connected to Toshiba cable modem.
2) PC#1 - Dell Dimension 4300, Win XP Home Edition SP2, Windows firewall disabled, EZArmor firewall on with network identified for sharing, specific folder identified, connected to router via ethernet cable.
3) PC#2 - Dell Dimension 3000, Win XP Home Edition (not sure of SP#), Windows firewall exceptions set to allow sharing, specific folder identified, connected via Netgear RangeMax Wireless PCI adapter (WPN311)
I updated the security settings on the router to use WPA encryption & MAC addresses. Added MAC address of PC#2 to list - did not add PC#1 because it did not come up as connected (that's how I entered MAC address for PC#2 - the router config site identified who was connected at the time I updated the security).
PC#1 - Internet works. Network Places only shows shared folders from PC#1 itself. Workgroup computers shows both PC#1 & PC#2, but PC#2 gives error when I try to open/explore (... not accessible. You may not have permission to access this network resource ... path not found.)
PC#2 - Internet works. Wireless signal say 'Excellent.' Network Places shows nothing. Workgroup computers shows nothing.
Any thoughts on why PC#1 cannot get into PC#2? ...why PC#2 does not see either computer (not even itself) under the workgroup or Network Places?
