Troubleshooting: QODBC POS Reports "Test Connection to QuickBooks POS failed" error.

Problem Description:

QODBC POS reports a "Test Connection to QuickBooks POS failed" error when trying to connect to QuickBooks POS:

Solution:

This error shows a problem when QODBC POS tries to access QuickBooks POS.

If you are in a Windows XP system, please check your connection string to see if it is set correctly or leave the "Current company setting" in QODBC POS Setup Screen->"General" window blank to make QODBC directly access the company file that is now running in QuickBooks POS.

About connection string settings:

1) Server Name=Remote machine name (On the QuickBooks POS machine, right-click “Computer,” select “Properties” option.  It will show the computer name)

2) Company File Name=Name of the Company (For example, if the company file name is “test,” then input "test" into this option)

3) Version Number=QuickBooks POS version (If you are using QuickBooks POS version 10, input 10 into this option).

Please keep QuickBooks POS running the first time you use QODBC POS to access. And make sure QuickBooks POS is in multiple-user mode when you use QODBC POS for remote access.

If you are in a Windows 7/Vista system, besides the method above, please also go to QODBC POS Setup Screen->"About" window. Check if it reports QODBC POS expired or "Fail to open license" error like this:

If it is, please log into your system as Administrator, or run QODBC POS Setup Screen as Administrator to fix this problem:
