It is essential to run this mistake rectification technique by replacing the [IP address or hostname] part with the QuickBooks server’s real IP address or hostname. For instance, if you wrote “” as the IP address in the step above, you would enter it as “ping” in your CMD window.

  2. If you get the message “Request timed out,” it signifies that the server did not reply to your ping requests. This could indicate a connectivity problem that produces the warning “server manager cannot run because of an error.”
  3. When you get the error messages “Destination host unreachable” or “Ping request could not find host,” it signifies that the workstation cannot connect to the provided hostname or IP address due to a network configuration problem, rendering the QBDB server unreachable.
