Issue with Folder Redirection very slow on one server

Question

I've got 7 Windows 2019 servers running RDS and we do Folder Redirection to our Synology NAS. We have had an issue on one server (all servers are in same OU and have same policies applied) where folder redirection is horribly slow. Files often freeze up and have issues. We've wiped the server and started from scratch and had the same issue. Then bought a new server and issue persisted. If I turn off folder redirection for that one server by moving it to an OU without it things seem to work fine.

Any ideas on what it could be?

Things I've tried

Disabled IPv6
Changed Fiber cables
Changed NIC
Bought New Server
Reloaded Windows 3 times on new server

All the other servers connect to the same file shares so there really is nothing different.

Any help would be greatly appreciated

Thank you

Answer 1

made a change that seemed to fix it, but not sure it's a good idea

set-MpPreference -DisableRealTimeMonitoring $True

You can resolve this issue by modifying the following registry entry, which controls the time wait.

HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer

FolderRedirectionWait (REG_DWORD) in milliseconds

Default value is 5000 milliseconds or 5 seconds for each folder.

Valid values would be from 0 to as high as you want to go which would be the DWORD maximum.

Note: We can set this value to 0 if there is no wait desired or as low as about 1000 which would be up to 1 second wait per folder.

Option 2
Pre-create the target redirected folders so that they are over 5 seconds old when the redirection occurs.

Option 3
Clear the Move contents... checkbox on each of the redirected folders. Side effect of this is that the folders can remain in the user's profile where they can see duplicated names when viewing the user's files.

Note: You can delete these files without causing any harm after the redirection is successful.

What do I do about the laggy SMB share speed where I get a spinning wheel when a user opens a file? This is resolved by disabling real time monitoring. Just not sure I want to leave that off.

Thank you for your waiting and reply, if it is really slow, you can turn it off manually

Hope this information can help you
