After rebooting a Windows guest operating system, you might experience the following symptoms while working with mapped network drive:
This issue occurs when the user logs in and creates persistent mapped drives before the VMware Tools service has fully initialized and started the Shared Folders client. As a result, when a File Explorer window is launched it displays VMware Shared Folders drive as disconnected.
To refresh the disconnected drive, click on the VMware Shared Folders drive marked with the red X or press F5 function key
The drive is available in Windows Explorer. UNC path access to the VMware Shared folders is available to the user.
Note: Windows Explorer will not do this automatically for mapped drives. It only refreshes the mapping when a user accesses the drive.
