Several users on the network use QuickBooks. Everytime somebody logs out all other users get booted.
The error message is as follows:
Connection Has Been Lost:
The problem may be caused by the way QuickBooks is set up on your network.
For the most reliable setup, you should install QuickBooks on the computer where the company file is located and perform a quick one-time setup. Click Tell Me More for instructions.
If you have already set up QuickBooks on your network, make sure that the computer that is hosting access to the company file has not been disconnected from the network or turned off.
