H4U

Active Directory domain, roaming profiles in the group policies. or profile redirection also in the group policies... one of those but not both. 
 
that in short.

The motherboard product page mentions both M.2 slots and what they can and cannot support:
The redline stuff is the most important stuff.
 
The top slot support M.2 SSD's of the PCIE variety, either at Gen 3 x4 or x2 depending on the CPU, while the bottom slot supports M.2 SSD's of the SATA variety.
I just kinda knew the WD Green is SATA based, but that info can usually be found on the product website too:
 
(It's often also easy to kinda guess if it's PCIE or SATA, depending on the speeds. SATA caps at ~560MB/s, PCIE can do more. Sometimes the B+M key also gives it away, but both the speed and key are not exclusive to M.2 SATA)

Are you using the top M.2 or the bottom M.2?
This board + this M.2 (WD Green) will only work if you are using the bottom M.2 slot.
