Thanks for joining the thread, @ashokiyer.

I hope you're having a beautiful day so far.

The best way to remote access your client's QuickBooks Desktop is through one of our third-party apps. You can search for remote access apps that allow you to access your client's computer remotely. Each app will give you details as to which ones require the equipment at the remote to be turned off or not. You can also contact their support team and ask them any questions you may have about their product. 

You can also reference other user's suggestions above to help determine the best access.

I'm only a few clicks away should you have any other questions. Enjoy the rest of your day!
