After working with Windows Server since NT 3.51, this was kind of a first for me. Here's the scenario:
- After no issues accessing a Windows Server 2012 R2 network share for 2 years, a Win 7 Pro workstation all of a sudden can access the mapped drive to the share, but cannot see all subfolders underneath it. Only one is visible, not the other 20 or so.
- When I log out as the user and login as the domain admin account, the issue persists on the workstation. Just this one workstation.
- Nothing has changed in terms of the share or NTFS permissions on the server-side of things.
- I look in the server event logs as well as the workstation's and don't see anything striking.
- I removed the workstation from the domain and add it again. The issue still persists.
- The workaround is that I created a second share to the same resource on the server-side of things. Mapping a different drive letter to this new share, the workstation can see everything again. So I figure it isn't NTFS permissions. And on both shares the Everyone group has Read and Change rights.
My only guess would be some sort of old school SAM database corruption or something? I recall years ago I had a Windows 2000 Server that would lose Computer Browser functionality due to some odd SAM database corruption. The only solution back then was to reboot the server. It was the PDC and couldn't even browse its own network shares.
I ran the Powershell commands listed here on the server, and no integrity issues were found --> http://www.rebeladmin.com/2018/03/integrity-check-detect-low-level-active-directory-database-corruption/.
