One of our hypervisors in ESXi went down, taking out W2k12 file server with it. Every vMotion got the fileserver back up, none of the network shares on the server were accessible. Users (and Domain Admins) would be confronted with an error message:
Connection to share \tx-fs1\G was lost. Status 0xC00000C9 Network name deleted
More commonly, the following error would pop up:
Windows cannot access \tx-fs1.company.local\g\ You do not have permission to access \tx-fs1.company.local\g. Contact your network administrator to request access.
Thing is, 'g' (which is physically G:\ on tx-fs1) has the correct permissions, or that they haven't changed at all from when things were working a few hours ago. G:\ (actual drive from server's point of view) is shared with Authenticated Users+Domain Admins both with full read and write access on Shared Permissions; on NTFS Security permissions, Authenticated Users only has read+execute, while Domain Admins has Full Control.
This is what I have tried (in order):
- Turn off sharing of G:\ (--> OK), then turn it back on and restore previous permissions; no success
- Re-add Authenticated Users and Domain Admins to NTFS and Shared permissions; no success
- Tried disconnecting from the mapped network drive on a VDI and manually readded it; no success
- Rebooted the server manually with shutdown -r -t 0; no success (still can't access the 'g' network share)
- Add Everyone with read+execute access to NTFS permissions; no success
- In addition to the previosu note, add Everyone with full read and write access to Share permissions; no success
- Created a folder "Test" in C:\ so that C:\Test exists, shared it with Everyone on read+execute on both NTFS and Share permissions; was able to access this no problem
(PS. The folders contained inside G:\ or \ do not inherit permissions from root)
Have tried logging off and logging on several times under different users (Domain Admin and regular ordinary Domain User alike).
Any suggestion or advice would be greatly appreciated. :(
