How to fix QuickBooks database server manager stopped?


You were working on QuickBooks and suddenly the application crashes due to the QB database server manager. Keep in mind that you are not alone in this situation. Several QuickBooks users have reported this problem when using QuickBooks on Windows-based computers. 

Such errors, in which the QuickBooks database server manager service fails to start or refuses to open, indicate that the Windows firewall is interfering with the service and preventing it from connecting to the internet.

If the QB database server manager service is not running on your computer or is disabled for some reason, you can only use QuickBooks in single-user mode; switching to multi-user mode will result in an error message that reads “QuickBooks Database server manager stopped” or “Windows Firewall: Disabled exceptions not defined” when you switch QuickBooks to multi-user mode.
