Sage 300 CRE - workstation actian services require domain admin

We have some issues with Sage 300 CRE v22.2 where the client workstations won't connect to the company folders unless we change the Actian service logon user to a domain controller. We receive an IO error status code 94.

I've read over some of the documentation but it seems to indicate this should only be required on the server and not the clients.

Wondering if others here have the same/similar situation or issue and could advise?

Thx, J
