So you're saying that before you upgraded the desktop to Windows 7 the Windows 10 laptops were able to connect to the shared drive? You can find some ideas for solving networking problems between different Windows versions here: http://windows.microsoft.com/en-us/wind ... nt-windows
I would recommend turning off the Windows Firewall for starters. For my own purposes I no longer "map" drives, I merely create an icon that opens the share via the UNC directly: http://resources.esri.com/help/9.3/arcg ... hnames.htm
For example I have a Windows Explorer shortcut on my desktop that directly opens the shared Music folder on my server. In the Target box of the Windows Explorer shortcut I have entered "%systemroot%\explorer.exe /n,/e,\\MYserver\Music", where "MYserver" is the server name and "Music" is the share name. When I double-click on that icon Windows Explorer opens showing the root folder of my Music share, no drive letter mapping required. You can see the command syntax for Windows Explorer here
. With the Win8 and later File Explorer you may have to use the "Pin to Start
" feature to get the same control over the initial appearance. Scott.
