I've wasted ten hours on this. We recently had to move our quickbooks installation to a new set of machines, and I just can *not* get it to work. We have two users, and I've tried hosting on each of the two machines, with identical results. We're using the most recent version of QB desktop (2024 Premier, Oct. 4th update, I believe), from just a few days ago.
When I login with the primary user on the hosting machine, it comes up with that username and (Multi-User). Hosting shows as "On" in the menu. But when I try to connect to it with the second machine, I get an error -6190,-816. The same thing happens if I try hosting with the other machine, only in reverse. If I don't login on the hosting machine, I'm able to connect with the client machine, but then if I try connecting with the host machine, it says there's an error.
Both QBCFMonitorService and QuickbooksDB34 are running as services on my host machine, but when I try running Quickbooks Database Server Manager, it says the qbcfmonitorservice is *not* running. It absolutely is! The other odd thing is that if I attempt to launch Quickbooks Database Server Manager from the Tool Kit, it says it's not installed, but as I just mentioned, I can run QDSM from the start menu no problem.
I've tried uninstalling QB and reinstalling. I've tried running the Clean Install Tool, and yet nothing seems to work. I can log in with one machine or the other, but not both (so I guess this indicates that the firewall settings are okay?) Running the latest version of Tool Kit 1.6.0.5 and QDSM.
Can anyone help? As I said, I've wasted 10 hours on this. We've been QB users for 20 years, so I'm very familiar with the program. We had it working on our other (older) 2 machines. I'm a computer engineer and have tried literally everything that my google/reddit/ChatGPT searches have mentioned as a possible solution. I'm not a neophyte. This is ruining my Thanksgiving weekend. I'd be most grateful if anyone had any suggestions not mentioned above.
