My SBS 2003 domain has 10 XP Pro computers and 1 Windows 7 Pro 64 bit computer.
Network neighborhood is reached as follows:
My Network Places > Entire Network > Microsoft Windows Network > MyDomain
It produces a list of most computers but it is missing my computer, and one other computer. These two computers have files that should be shared.
I have compared the firewall "file and printer sharing" settings between both visible and invisible computers, and they look the same.
I also compared my computer > properties > remote and it looks the same on both visible and invisible computers.
SSDP Discovery Services is running on both
Even going to Windows Explorer and typing \\cpuxxxx\ does not show the shared files -- it says "windows cannot find cpuxxxx"
I have tried it from several computers including a Windows 7 64 bit pro. I have tried it with both Adminstrator signon and JaneDoe's signon with same issue.
