Why do I have to use QB connection manager, file doctor or the server manager every two weeks of so to be able to get QB to work in multiuser mode? Nothing is permanent.

Have contacted Tech Sp numerous times and they log on to my server and say that they will provide permanent fix.  Unfortunately, a week or days later, the same issue arises where we cannot access QB in multuser mode.  Have to go to server use File Doctor or Server Manager or Connection diagnostic to get multiuser access again.

Would like to see a better fix that that published for H606 or whatever errors.


Hi there, dagregory

I appreciate for letting me know the steps you’ve tried to resolve the multi-user issues. I’m here to ensure that you’ll have a better fix to any errors, including H606.

First, let’s make sure your computer hardware, software, and operating system meets the minimum requirements for your QuickBooks Desktop version. You can check out this article for more information: System Requirements for QuickBooks 2016 and Enterprise Solutions 16.0.

Once done, it’s important to update QuickBooks Desktop and its QuickBooks Database Server Manager. Generally, these are necessary when a new year of QuickBooks Desktop is installed on the workstations or if an update to a current year is released. This way, these can help resolve any future multi-user errors.

Here’s how:

  1. Download the patch from updating the QuickBooks Desktop by checking on the Product information window. Note: The patch for the server is the same as the patch for the workstation.
  2. Reboot the server after the patch installation completes.
  3. On the workstation, after the server has been updated, you may get the following message, “The company file needs to be updated to work with this version of QuickBooks Desktop.”
  4. There will be a prompt to create a backup which is required since these updates can modify the database structure.
  5. Follow the prompts and after backup is completed, you should be able to open the file.

If you’re still encountering any H-series errors, you can go through these articles for detailed instructions:

People come to QuickBooks Learn & Support for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:

  1. Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
  2. Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
  3. Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
  4. Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
  5. Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
