Hi Desmond, Make sure that on those Win10-boxes the SMB-Caching is switched off. If not, that would lead to index corruption, which in turn crashes the application.
The easiest way to set those settings is by running this MSI package, which just sets three RegistryKeys: https://www.dropbox.com/s/aa9vwwup1u8h2zy/OPLock_Set_SMB2-infocache.msi?dl=0 The benefit of that MSI is, that you can deploy it as a GPO (GroupPolicy), targeted for any Domain-Computer.
If you want to set those keys directly, then on every Client-PC (not Servers!) at HKEY_LOCAL_MACHINE\system\CurrentControlSet\Services\LanmanWorkstation\Param eters
Set this keys to a value of 0 FileInfoCacheLifetime FileNotFoundCacheLifetime DirectoryCacheLifetime
In your App you could query those RegKeys and show a warning if not zero. (You normally can't change them from your app, since they are at machine-level and therefor need Admin-rights to modify)
With kind regards from Bavaria

Have an issue with an application. They are reporting that when running under Windows 10 (Pro) the app is intermittently crashing, while the Windows 7 machines are running just fine.
Am supporting another app using both OS's and works fine.
Not even sure at what I should look at. Am reviewing the tables for any oddities,
Any suggestions/thoughts? TIA, Desmond
