Attempt to add a SMB Share, take all defaults with default permissions checked.
On new GUI, you get the spinner for awhile, then the spnner stops but you remain on the Add SMB share save screen. The share is created but if you try to edit it, the default permissions check box is unchecked.
On old GUI, after while you get a CallTimeout exception see attached. Again the share is created but default permissions remains unchecked.
If I then check the default permissions and save, you get the same error repeatedly every time.
I have tried this a dozen times and get the same error. I stopped, then restarted the SMB service with no effect.
