Thank you guys for your assistance.
I created a small windows 7 VM and loaded it on my Windwws Server 2012.
It appears to be working as expected but, before I sign off on this mission, I would like to get the gang together on our side and test it with a few guys together and not just me alone.
If this works it means that Microsoft probably killed the JoinFS operations on the Server product with one of their last updates.
Will let you guys know what ASAP
