We’ve seen issues with the Clients recently (dropping shares, disconnecting, etc.) that were resolved by making changes to the Registry Key on the Windows 7 or Windows 10 Pro platform. For Windows 10, only one entry is changed.
Close any open software and launch Regedit:
To launch, type regedi’ in the Windows Start menu, double-click regedit.exe to open
For both Windows 7 and Windows 10 platforms, set the following registry key to ‘1′ :
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache
Double-Click ‘LargeSystemCache’ to make the change, Enter 1, Click ‘Ok’ to close.
For Windows 7 platforms ONLY, set the following registry key to ‘3′ :
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size
Double-Click ‘Size’ to make the change, Enter 3, Click ‘Ok’ to close.
Click the X in the upper right corner of the window to exit Regedit
