Looking at this:
dns forwarder = 22.214.171.124
server services = -dns
You only need one or the other, the first is only required if you use
the internal DNS server and the second says you are using Bind9
try removing 'smb2 leases = yes'
I would also remove 'dsdb:schema update allowed = true' , you only need
this to update the schema, which brings up a point, have you extended
the schema. If so, with what and how ?
