On a Windows Server 2003 fully patched, during the last 3 weekends, for some reason about 2/3 of the shares on the server are gone. The files and directories are still there with the proper permissions, but the shares themselfs disappear.
It is on the same shares every time.
The default hidden share for the drive is still there.
The shares are not all on the same physical drives or same logical drives.
Nothing is recorded in the System or Application logs of the server.
I do have auditing turned on for the registry key that corresponds to the lanmanserver\shares but that is going to be hard to track down as there are hundreds of thousands of lines and sine I do not know exactly when this is occuring I will have to search the entire list.
Everything is fine on Friday, then Monday morning when users start connecting the shares are not there.
