The issue was resolved by Intuit QuickBooks Technical Support instructing me to change the QuickBooks Database Server Manager Service (QuickBooksDB26) from logging on as QuickBooksDB26 to Local Account and Allow Service to Interact with Desktop.
So in effect, I was told by Intuit to change the LogOn settings of the Windows Service designed by Intuit from the default Intuit setting to a custom setting. First, I am perplexed as to why this issue arose out of nowhere when there have been no changes to the Server. Second, I find it odd that if this is a known issue by Intuit wouldn't the installer have set the LogOn to Local Account upon installation. Third, what is the purpose of the installer creating QuickBooksDB26 if it is now not utilized by the Service?
