The application encounters this issue, as its name indicates, when it is unable to establish a connection with the company file or access it for specific reasons. 


A "Cannot communicate with the company file" error message window appears on your computer when QuickBooks tries to access the company file, but your firewall prevents it from connecting. 


The error message looks like this: “It appears that the QuickBooks software on this computer is set up to allow shared access to the company file, but the QuickBooks software on your computer is unable to communicate with it.”


The limitations imposed by the third-party firewall on QuickBooks' operations result in several mistakes. Sometimes you are unable to use QBDT, and other times these difficulties stop QuickBooks from opening the company file. 


The error we will discuss in this article is known as "QuickBooks cannot communicate with the company file," a general communication issue that prevents QuickBooks from interacting with the company file. 


The firewall is not the only factor causing QuickBooks communication difficulties; other factors also make it difficult for QuickBooks to connect to the company file stored on the server at a separate location. 

Main Contributors to the Encounter Company File Connection Error

The server hosting the company file, which is also occasionally the cause of the QBDT services connection problem, is also accountable.


Here are a few typical causes for QuickBooks to display a company file connection issue:


  • When the server configuration is flawed or there are problems with the server's connectivity to other workstations in the network, an error occurs

  • To connect to the company file, QuickBooks needs Database Server Manager; if this procedure is not operating on the workstation, QuickBooks will encounter these kinds of connectivity issues

  • Not only does an outdated version of QuickBooks Desktop cause issues with company file connections, but it also causes printing, payroll, banking, and update difficulties

  • QBDBMgrN service is facing an issue when running it in the background 

  • The hosting settings are incorrect on the server or workstation system
