we've got a Samba Domaincontroller running on Ubuntu Server. There is multiple workstations accessing different Shares. There is one Server outside of the Domain which provides a share for Database Access. That Server is not joined to the domain which leads to huge performance limitations if compared between a Workgroup and a Domain Computer. Where is this technically coming from, are packets doing extra rounds because of the named situation? Is this solvable without joining the domain with the DB server?
