How to fix the problem with permanent disappearance of DFS folders on Linux?

Question

linux

Hello. Is available Windows Server 2003, on it DFS folders are configured. For Windows clients everything works fine. But who works under Linux Mint, folders fall off periodically after a certain time. What could it be? We poked around in the server settings but did not find anything. Maybe it's the settings of the client Samba? Thanks in advance.
