Issue with SetNamedSecurityInfo Returning Error Code 59 on Shared File

Question

Hello,

I am encountering an issue with the SetNamedSecurityInfo API while attempting to modify the security settings of shared files. I have five shared files, and the API works as expected on four of them. However, for one specific shared file, the API returns error code 59 (ERROR_UNEXP_NET_ERR: An unexpected network error occurred), even though the file is fully accessible via the Microsoft Management Console (MMC).

Could you please advise on why this specific file would trigger error 59 in SetNamedSecurityInfo while being accessible through MMC, and how I can resolve this issue?
