I am having trouble getting my computers to talk to each other using my home local area network. I'm using a wireless router, a D-link DI-614 + running the latest version of firmware v 3.43. Although this is a wireless router, I am currently having troubles with direct ethernet wireline connections to the router from a first desktop computer (family), a second desktop computer (business) and a laptop computer. All three computers are running: Windows XP home, SP2, with all critical updates installed; Zonealarm as a firewall in which all of the possible assignable IP addresses to the computers have been entered as a trusted IP range in Zonealarm.
The two desktop computers only have a single user (administrator) set up; the laptop has two users set up, both with administrator privileges. All three computers are shown by my router as having been assigned appropriate IP addresses and all three computers connected by wireline to the router have no trouble accessing the Internet through the WAN port of the router.
All three computers have been configured to be on the same HOME workgroup and have been rebooted several times in this configuration. So here is the status.
Viewing my network places on the family computer, I can see all of the shared file's on the family computer and on the business computer, but no shared files on the laptop. Viewing my network places on the business computer, I see no listed files on it or the other computers. Viewing my network places on the laptop, I see shared listed files on the laptop but no shared files on any of the other computers. Running the view network computers usually causes a not permitted response.
All three computers have NetBIOS enabled and all three computers show under "local area connection properties" the appropriate items enabled: client for my for Microsoft networks; file and printer sharing for my for Microsoft networks;/qoS packet scheduler; Internet protocol (TCP/IP).
It is my desire to be able to share files among the three computers. I tried totally disabling Zonealarm on the business computer but did not see any different results after it was disabled.
I would very much appreciate help in resolving this net working issue so that I can share files among the computers. All I want to do is share files and printers.
