Server 2012 File Server - suddenly stops serving requests (but otherwise looks fine)
Mighty weird one here - for the past day or so our Server 2012 staff file storage server has suddenly stopped working normally and prevents staff from browsing to it with access denied permissions errors. regardless of your personal permissions (in my case domain admin) its just not possible to access the file server over the network.
However....logging on through RDP I can still easily locally browse to the files, see that the permissions are the same as always. Even more weirdly is there is nothing obvious in the logs, no high CPU usage, no weirdness of any kind what so ever.
A restart promptly makes the issue go away (usually its about once a day with no particular pattern); our student file storage server which is configured identically hasn't shown even a hint of this issue at all.
Going to remove it from the domain and add it back on tonight to see if it makes any change but does anyone have any other ideas?
Worst comes to the worse I'll replicate the data over to another server and switch over but either way its a faf :)
The file shares themselves are hosted on DFS and one thing I will be trying next time it happens is if a direct server name UNC path works any better.
