Reasons
This error won’t let the server computer switch to multi-user mode and share the company 
file with the workstations. The reasons you encounter this multi-user network error in 
QuickBooks are mentioned below-
• The hosting settings in QuickBooks aren’t correct and workstations are running in multi-
user mode.
• The Database Server Manager fails to run due to an interruption in its background 
processes by security programs on your PC.
• The Transaction log and Network Descriptor files are damaged, and DBSM generates 
issues when it tries to run them.
Solutions
You won’t be able to set up a multi-user network to host the company file until your QBDT 
remains affected by this error. The applicable methods to get rid of the QB multi-user mode 
issue from your PC are given below-
Solution 1- Share the company file again after fixing the hosting settings
You must know that QuickBooks only allows hosting the company file on the server if it runs in 
multi-user mode and all the remaining workstations use the single-user mode. If this isn’t the 
hosting setup on your QuickBooks, you’ll see the error H505 QuickBooks coming up on the 
screen when you try switching the server to multi-user mode or opening a company file. You 
need to ensure that the QB hosting settings are correctly arranged to prevent the development 
of multi-user mode errors. Refer to these steps-
• Run QuickBooks on the system (Workstation) where you initially encountered the error.
• Click the File menu and select the Utilities option in the drop-down list.
• Tap the Stop Hosting multi-user access option and turn all the workstations to single-
user mode using these steps.
• Run QBDT on the server and access the File menu.
• Select Utilities in the options and click Host multi-user access.
• Restart all your computers after configuring the hosting settings and run the company file 
in multi-user mode on the server.
If the error code stops you from hosting the file again, jump to the next solution.
Solution 2- Restart the Database Server Manager’s background 
processes
Database Server Manager ensures the multi-user network is correctly set up and the 
systems access the company file without problems. If minor issues or bugs on your system 
interrupt its background processes, the multi-user network crashes instantly, and the error 
code comes up on the screen. You need to restart the DBSM processes as shown in the 
following steps-
• Press the Ctrl+Shift+Esc keys together to launch your PC’s task manager.
• Move to the Processes tab and look out for QBDBMgrN.exe, QBDBMgr.exe, 
QBUpdate.exe, etc.
• Right-click on them individually and tap the End Task option to stop them from running.
