Might have to make sure the Workgroup is the same on all computers also.
I checked that on two home laptops one of them has windows 7 and other has windows 10,,,both of them have same workgroup as my desktop
Windows 7 laptop (not work laptop) can access shared folder
Windows 10 laptop (not work laptop) can't access the shared folder
Windows 10 laptop (work one) workgroup can't be used as it part of a domain,,,,can't access the shared folder as well

Means I am having problem with windows 10 OS ?
