Issue with SetNamedSecurityInfo Returning Error Code 59 on Shared File

Rishi C 0

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?

What kind of the specific shared file? What's the difference between the specific shared file and the four of them?

Am so sorry, Am a developer from product company. I guess, Am not allow to sharing the product code.

Also am mentioned specific share file is not a uncommon one. It's looks like common shared files.

For example :

Share1 ( SACL enabled Successfully )

Share2 ( SACL enabled Successfully )

Share3 ( SACL enabled Successfully )

Share4 ( SACL enabled Successfully )

Share5 ( Failed due to error code 59 )

But able to view the shared file via MMC

So... what's the difference of the specific shared file of data type identifies? Error code 59 means an unexpected network error occurred. Is that the shared in a group or domain which need privilege to access?
