error codes -6190 and -816 after using QB file doctor and QB Desktop Install Diagnostic Tool. I have also tried restoring my company file and reinstalling QB on both machines that need to run QB at the same time.
Thank you reaching out to the Community. First we need to make sure that your QuickBooks is up to dated. This will help you fixed minor issue on your files. After that you can follow my colleague steps provided above on how to rename the file. You need to ensure at the end of the file you add word OLD. EX. company_file.qbw.tlg.OLD.
Now, go to any computer on the network or directly on the server and run Quickbooks and it is fixed until it happens again. From now on, just right click the fixquickbooks.bat file (looks like it has gears on the icon) and Run As Administrator. People will forget to run as administrator, so you might rename the batch file from fixquickbooks.bat to "Right-Click and run as Administrator-fixquickbooks.bat" to help you remember.
The symptoms are that even when you run Quickbooks Database Manager and scan the folder for quickbooks databases, the Network Diagnostics Failed message comes up and leads you to believe that there is a firewall issue. This problem has been around since before 2008 and still happens today 13 years later.
I've spent countless hours and $$, including having my IT guy come in and uninstall and reinstall QBs on the server and the two workstations that use the files from the server, as well as countless hours on QBs tech support chats and phone calls utilizing glance, and I am still unable to switch back and forth between user names without getting this message and being unable to get back into QBs. The reason I have to switch between user names is because I am trying to run a PPP report that must be generated in order to get forgiveness of our PPP loan and am told I must be signed in as Admin. However, I crash every single time I try to generate this report and then spend hours trying to get back in as anyone. I'm beyond frustrated and my boss is going to lose his opportunity to have his PPP Loan forgiven because we cannot generate a report that Intuit Capital insists we need to apply. Thanks QBs
Let me share additional troubleshooting steps to help you get rid of the error you've received. It's important to perform these on the main server or the computer where QuickBooks and the company files are saved.
Now, let's create a back up copy of your company file. Then, download and install QuickBooks Tools Hub, then run the Quick Fix my Program. This is a built-in tool that auto-detects and auto-fix data damage issues within QuickBooks.
Our hard drive went out. My tech guy got me a new one, and reinstalled QB. My host computer is in multi-user, but my front 2 computers say I need to switch to multi-user on my host computer. I have a 3 user license. What do I need to do to open all 3 computers?
If the main computer and one other computer are open in Multi User, why are we getting messages saying they are in Single user? We have to reboot the system for us all (5 total) to get in. Everything is updated. And our router is brand new. This has been going on for a couple of months, when before we had no issues. The error codes are 6190 and 816.
If the main computer and one other are already logged in, in Multi User, why are the other computers getting a message that they are in Single User? Everything is updated. This has been going on for a couple of months, where before we had no issue logging in. The error codes are 6190 and 816.
The problem is there are two computers with Quickbooks open and they are not in Single User. They clearly show Multi User at the top of the screen. But, the other 3 computers show a message saying the first two are in single user. Will renaming the files correct the error codes being wrong?
It sounds like the five computers aren't signed in to the same company file. The issue could be that the company file is in different locations, causing the other computers to be logged in the incorrect location. Let's make sure all computers are logged in to the same company file in the same location. You can do this by opening QuickBooks and clicking on the company file from the No Company Open screen. You should see the file location at the bottom of the company file list.
Please note: On a multiuser network, one computer hosts your company files. This is your server computer. Computers that connect to your network that don't host your company files are called workstations.
However, if you feel you need a little extra help with the setup, please know that you can reach out to our Technical Support Team. Our tech support agent has the tools to screen share with you and complete this process for you. You can use the link I've included below to connect with an agent.
You can utilize the trial period of a simple private cloud solution to isolate the issue. Users will access your host computer by internet connection. If they are able to work in multiuser mode, the problem is on your LAN environment.
Since the error persists, I'd recommend contacting our QuickBooks Support Team. They're equipped with tools to check your file and determine its cause. It'll also allow them to submit a ticket to our engineering team to alert them about the issue if necessary.
In the meantime, I'd recommend following the steps in this article: Fix company file and network issues with QuickBooks File Doctor. This will allow you to download the QuickBooks Tool Hub to resolve common errors in the system.
In addition, if you're experiencing any performance issues and you wanted to reduce your file size, you may condense the data. Here's a link that provides complete details on how to perform this process: Resolve QuickBooks Desktop performance issues: Manage your data file.
I am amazed that none of the solutions from Intuit admins included the suggestion to use the Quickbooks Database Server Manager as a solution.
I had a persistent problem with -6190, -816 errors from one of my client computers after a fresh update of Quickbooks Enterprise 2023. None of the typical spammy fixes worked. I say spammy, because the renaming of the TLD, and ND files to OLD fixes are repeated on many spam websites with link bait about -6190 and -816 errors.
The Quickbooks Tool Hub is also a lame utility that tends to redirect users to a third party support company. It is a legit Intuit application, but it is meant to redirect users with problems to a subcontracted third party.
In any case, the Quickbooks Database Server Manager includes a diagnostic that you can run that will find any problems with connectivity between client computers and the computer with the company file including firewalls, virus protection, etc. In my case the QDSM fixed whatever issue was causing the client computer to have problems. This connectivity issue is hard to recognize since the client computer would connect in single user mode but not multi-user and it too several regression tests of sequencing connections, etc. until I got a message on the client computer to use QDSM.
QDSM is located on the Windows Start Menu. Highly recommended to try it first for fixing -6190 and -816 errors.
I've had this problem intermittently for the last 2-3 years. The error says that another user is in single-user mode, which I've verified time-and-again is not the case. It is resolvable by me asking the user on the host computer to "toggle" single-user mode (change from current multi-user mode to single-user mode then back to multi-user mode) and then suddenly I am able to open the company file using my account. But is it a pain and interruption for both me and the other user. It can happen multiple times a day, or just a few times a week, I see no rhyme or reason to the issue.
And you're also right, the boilerplate responses form QB support on this thread and others just runs down a generic list of fixes that I just don't have the confidence to enact. The last thing I want to do is screwup the database while trying to fix an annoyance.
Note to QuickBooks support team - it would be helpful if one of these responses included some explanations of why the issue might be happening, if it's a known issue and under what conditions, and some specific ways to fix it. And please don't respond with the boilerplate "this means a user has the company open in single-user mode" because we know that isn't the case and this wouldn't be a support issue if the program was behaving as designed.
The real fix for this is to remove the previous version on the QB Database manager the old one gets left behind in the upgrade. Then reinstall the new. Can't understand why they haven't figured this out yet. No one can troubleshoot these days lol.
In my case the QDSM Scan Folder function always works to let my user back in as multi-user but give it an hour or so and everyone who left the file is again being told the file is in single-user even though clearly there are several people already using the file. So every day for weeks they text me I do "Scan Folders" again and they are able to continue working. There has to be a reason it keeps falsely shutting them out
There may be some minor data issues with your company file that's why there are times that you're having trouble scanning your file. Try running the Rebuild and Verify Utility tool to fix possible data damage on your company file.
