Common symptoms
- QuickBooks reports that the connection to the company file was lost
- Users are disconnected intermittently
- The problem returns after the server sleeps or restarts
Before you begin
- Have every user save work and close QuickBooks
- Note whether all users disconnect or only one
- Record the host name and company-file network path
Back up your data before changing company-file components, services, firewall rules, or permissions. Never delete the .QBW company file as a troubleshooting step.
1. Determine whether the failure affects everyone
If every workstation disconnects at once, begin with the host, its network link, power state, and database service. If only one workstation disconnects, start with that computer’s connection and path.
- Ask users for the approximate disconnect time.
- Check whether the host restarted, slept, lost network connectivity, or logged an error at that time.
- Confirm the network share is reachable before reopening QuickBooks.
2. Keep the host awake and available
A host computer that sleeps or hibernates can interrupt every QuickBooks session.
- On the host, review Windows Power Options.
- Prevent sleep, standby, and hibernation during business use.
- If the host is a laptop, confirm lid-close and power-source behavior are appropriate.
3. Verify folder access independently of QuickBooks
A simple file test can reveal share or permission trouble without risking the company file.
- From an affected workstation, open the shared folder.
- Create and delete a harmless text file.
- If that fails, fix Windows access or connectivity before troubleshooting inside QuickBooks.
4. Review hosting and Database Server Manager
The host should be configured correctly and the QuickBooksDBXX service should remain running.
- Confirm only the intended host is hosting multi-user access.
- Restart the matching QuickBooksDBXX service on the host.
- Rescan the company-file folder and retry with one user.
Verify the result
Test one workstation before bringing everyone back in.
- Open the company file from its normal network path.
- Switch to multi-user mode and sign in with a separate QuickBooks user.
- Close and reopen the file once to confirm the repair survives a fresh connection.
- Record what changed and keep a current backup.
