Problems Connecting QuickBooks Point of Sale Workstation to Data File

QuickBooks Point of Sale POS

I received a QuickBooks Point of Sale support call this week from a customer who was having difficulty connecting the client workstation to the POS data file which resides on a 2nd computer (the “POS Server workstation").

This happens occasionally when for whatever reason the POS Server workstation gets rebooted while the client workstation still has POS running.  When this happens the connection is “lost” between the “client workstation” and the “server workstation.”

Repairing QuickBooks Point of Sale Server Connection to Client Workstation

In most instances, rebooting the client machine will solve the problem.  However, if this does not solve the problem, follow the steps below in this exact order:

  1. Close Point of Sale on the client workstation.
  2. Reboot the server workstation.   
  3. When #2 is 100% complete reboot the client workstation.
  4. Launch Point of Sale on the client workstation and it should connect to the POS data file on the server workstation automatically.

Invalid Product Code or Invalid Product Number Errors

Another connectivity issue that QuickBooks Point of Sale customers face is the Invalid Product Code or Invalid Product Number error, also known as Error Code 176109.  This error sometimes appears when upgrading Point of Sale to a newer version, or adding a client license to an existing Point of Sale network.  This also can happen when trying to open or register Point of Sale. 

This error can result from using an incorrect product code.  Verify the product code by clicking on Help > About Point of Sale and looking for the words “Product Number”.  If the product number is correct, make sure you are logged into Windows as the administrator.  Once you have eliminated adminstrator rights as a possible cause, the most likely culprit is damaged files in the Point of Sale Client Entitlement Folder.

Windows 7 and Vista

To repair these damaged files on Windows 7 and Vista operating systems, click the Start button > Control Panel > Folder Options.

Choose the “View” tab and select “Show hidden files, folders, or drives and click OK. 

Click the Windows Start button > Computer > Local Disk (C:) > Program Data > Intuit > Entitlement Client > v8 and press Ctrl + A to select all of the files in the folder.

Right click the mouse with cursor inside the highlighted folder area and click Delete. 

Now launch QuickBooks Point of Sale.  If the problem persists, you will need to uninstall the Point of Sale software and re-install it.

Windows 8

To fix this on Windows 8 position your mouse in the lower left hand corner until the Start box appears, click on the Start > File Explorer, click on the View tab and check the Hidden Items checkbox.

Browse to Local Disk (C:) > Program Data > Intuit > Entitlement Client > v8 and press Ctrl + A to select all of the files in the folder. Right click the mouse with cursor inside the highlighted folder area and click Delete.  

Now launch Point of Sale.  If the problem persists, you will need to uninstall the Point of Sale software and re-install it.
