Multi-User / Network Decision Tree

Guided

Can the file open directly on the server?

No = file/program issue. Yes = workstation/network/permissions issue.

Can the workstation ping server by hostname and IP?

Hostname failure points to DNS/NetBIOS. IP failure points to network/firewall.

Are hosting roles correct?

Server hosts. Workstations do not host.

Rescan and rebuild sidecars

Rename .ND, rescan in Database Server Manager, then retry multi-user.
