1147 connect to router and internet but not to desktop

I am at my wits end.  A few days ago, I lost the ability to print over my wireless network.  When trying to access my desktop, I get the message,

Windows cannot access \\DELLDESKTOP

You do not have permission to access \\DELLDESKTOP.  Contact your network administrator to request access.,

I have no issue connecting to the internet through my wireless router.

I have tried so many options the internet had to offer.  I restored it back to an earlier date - no change.  I refreshed windows- no change.  I did a clean install of windows - no change..  Now I am contemplating using my installation DVD to revert back to Windows 8 but I have gotten too use to Windows 10 so I want to make sure I have exhausted all options.

Laptop - Dell 2 in 1 3147 running Windows 10

Desktop - Dell Inspiron running Windows Vista

Any ideas?
