Files not showing up in networked drive - Fix with Group Policy?

Hello,


We recently fixed the issue described in this thread using the steps provided below. I am wondering if there is a way to make the below registry changes to all of the workstations in our office using Group Policy?

Or do I need to add these values manually using a .reg to each machine, then changing DontRefresh value to 0.

Steps:

Create registry keys below to control the cache lifetime:
Under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentcontrolSet\Services\LanmanWorkstation\Parameters:
* FileinfoCacheLifetime
* FileNotFoundCacheLifetime
* DirectoryCacheLifetime

They are all REG_DWORD type in seconds.

There is a DontRefresh key that should be set to 0
- Open Registry Editor by typing into Start > regedit.exe (or open directly in C:\Windows\regedit.exe)
- Hit Ctrl+F for the search dialog, type "DontRefresh", hit Enter
- After waiting a couple of seconds, the search finds one result: 'DontRefresh REG_DWORD 0x00000001 (1)"
- Double click on DontRefresh and change 1 to 0.
- reboot your PC afterwards.

Thanks in advance for your help!
