I appreciate your detailed description of your concern, @BrianHFASPS . You’ve done a great job isolating the problem so far. Since QuickBooks Desktop is scanning a very large number of files locally and over the network, performance can be impacted by data integrity issues or connectivity glitches, even on a fast wired network.

To help us further troubleshoot and fix any underlying data or program problems, I recommend installing and running the QuickBooks Tool Hub. This is an official Intuit utility that combines several key diagnostic and repair tools, including those for network issues, company file errors, and program problems.

1. Close your QuickBooks.
2. Download the recent version (1.6.0.8) of the QuickBooks Tool Hub. Save it somewhere you can locate it.
3. If you've installed Tool Hub before, you can find out which version you have. Select the Home tab. The version will be on the bottom.
4. Kindly open the file you've downloaded. It is named QuickBooksToolHub.exe.
5. Follow the on-screen steps to install and agree to the terms and conditions.
6. Once done installing, double-click the icon on your Windows desktop to open the tool hub.

Step 2: Run Quick Fix My Program

1. In the QuickBooks Tools Hub, select Program Problems.
2. Select Quick Fix My Program.
3. Start QuickBooks Desktop and open your data file.

Following these steps can help improve QuickBooks’ responsiveness when accessing your file over the network. Please try them at your convenience, and feel free to reach out if you need further assistance or if the issue persists.
