This error can occur when:
The following steps are to be used if the QuickBooks File Doctor can't run successfully on your computer or you prefer a manual solution.
If your firewall or security software has been configured and the error persists, continue to step 3.
Note: Starting with QuickBooks 2015 the installer now automatically runs the network portion of the QuickBooks File Doctor. This means that when installing the program exceptions are entered into windows firewall that are needed to work properly. If you have a 3rd party firewall program like Norton or McAffee you may still need to manually enter those exceptions.
If your permissions to access the company file or folder are set up correctly and the error persists, continue to step 4.
You need to scan the folder where the company file is stored to created the Network Descriptor (.nd) file. The .nd file stores information about the computer that is hosting the file.
Note: If you do not see the QuickBooks Database Server Manager in the Programs list, you might have to uninstall QuickBooks and reinstall selecting the second option I'll be using QuickBooks on this computer, AND I'll be storing our company file here so it can be shared over our network.
If you scanned the folder and the error persists, continue to step 5.
In a network environment, the computer (server) with the QuickBooks Database Server Manager installed must be the only computer with the hosting feature turned on. Scanning the company files turns hosting on.
Step 5.1. Computer workstations
Step 5.2. Server
If the error persists, continue to step 6.
Step 6.1. Open the file from the hosting computer
If QuickBooks Detects no problems with your company file, and the error persists, go to Copy file to another location.
Step 6.2. Copy file to another location
Important: Be sure the original company file name is renamed before you copy the file that was recently opened from the desktop. Do not paste over the existing company file.
