User cannot open QuickBooks company file on server share

Scenario

QuickBooks launches, but opening the hosted company file returns a multi-user or file access error.

Recommended Resolution Path

1. Verify the QuickBooks Database Server Manager service is running on the host.
2. Check share and NTFS permissions separately for the user and service account.
3. Confirm the file path is excluded from antivirus scanning on both server and client.
4. Use QuickBooks File Doctor only after confirming the issue is not pure permissions.

Technician Notes

Confirm the business impact, document the root cause, and capture any preventative follow-up in the PSA or client knowledge base.
