Re: Mounting a Windows Share
After a reboot, one of my shares will no longer mount. And of course,
it's the big one, the NAS box. Here is output from `strace mount.cifs
//DISKSTATION1/BigVol1 /mnt/bigvol1 -o
vers=2.1,username=***,password=*** (*** is real username and password
covered up):

The volume is still quite useable from all Windows systems, but
somehow since my last reboot, something has changed that I cannot
identify. As always, help greatly appreciated.
