Assuming you can get to the share from another PC via Start > Run > \\192.168.0.52 and at that point see the share of Pictures
Then the path looks good. But...
Since the login name is @cox.net, that implies domain accounts, or that you are using Windows 8-10, and in that case it would typically be needing port 445 and not 139.
Some machines won't allow 445, and if that is the case you would need to depreciate the OS to use SMB1 (port 139)
I don't know the machine enough to be certain, I believe its a no though, about 4 months ago I tested what I believe was at the time the latest spar firmware and it would still not allow it. I work for Xerox but not on this model, and couldn't find one local, so I had to do testing using one in an office 3000 miles away and get the person to try it with me. Failed.
Ended up enabling SMB1 per the link I gave up above.
Can't hurt to call Xerox though, it may have been resolved in an update.
