My CIFS mount for ISOs stopped working recently. I tried to detatch it and re-attach it, however I get the following error: https://i.stack.imgur.com/2529G.jpg
I tried looking this error up, however I cannot conclusively determine what is failing. I have restarted the host xenserver as well as the host serving the target. So far as I can tell this is the only issue that is observed with our CIFS mounts. Furthermore, I tried manually unmounting the target at the CLI, but I don't recall the exact method I used.
xenserver 6.0.0-50762p
I do not know what exactly caused this issue as other services have not been affected.
