Deactivation of SMB2 directory caching on important clients
in the past we have experienced a few issues where time critical clients did not react quickly enough to updates on the filesystem.
In some of those cases the reason was a windows default setting for the SMB2 cache that prohibited the client to react fast enough.
Please read the following Microsoft article for further reference: https://technet.microsoft.com/en-us/library/ff686200%28v=ws.10%29.aspx
Good results were achieved by deactivating the cache setting on affected clients:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Lanmanworkstation\Parameters\DirectoryCacheLifetime = 0
This has recently been found to be effective under Windows 10 using DBM 'legacy' Archive tables.
