I have seen a few similar problems in these forums but not mine exactly. I have a home network with a desktop PC running XP Pro, a laptop running XP Home and another laptop running MCE.
Under My Network Places, XP Pro can see itself, and the two laptops and I can access the shared files instantly. XP Home can see itself and XP Pro, but not MCE, and likewise, MCE can see itself and XP Pro, but XP Home. If I go to View Workgroup Computers, all 3 appear in the list no matter which computer I'm on, but if I click on say MCE it literally takes about 3 minutes to appear. Then the shared files are instantly accessable but it takes another 3 minutes to close. This is the same from either laptop, and only marginally faster from the desktop. The Desktop is cabled connected to a wireless modem/router and the laptops are wireless, all using Windows to manage the connection.
Why don't all 3 machines appear on each machine and why is the connection so slow via "View Workgroup Computers"?
