I have two computers on my home network that I want to "see" each other: "Akoya" and "Dell." The workgroup name is MSHOME. After I run the network wizard on Akoya, I can start Windows Explorer, and under My Network Places, I can see "MSHOME" and under it, "Akoya." I DO NOT See "Dell."
After I run the wizard on Dell, and specify "Dell" and "MSHOME," I start Windows Explorer. I DO see MSHOME, but there is no "plus sign" ("+") next to it, meaning that it is non-expandable. When I click on MSHOME, the system waits a few minutes, then gives me a message, "MSHOME is not accessible. You might not have permission to use this network resource....."
In other words, the Dell computer can't even see itself... (?)
Do you have "File and Printer Sharing for Microsoft Netwoks" installed for that connection?
