Enable SMB2 on the Client
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanWorkstation
edit DependOnService and add MRxSmb20
so it should look like:
Bowser
MRxSmb10
MRxSmb20
NSI
ps. Bowser is NOT a Browser typo!
THEN
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\mrxsmb20
Change Start to 3. (it was 4 = disabled)
Reboot client
