Possible reasons for QuickBooks H505 error to come up in the 
software
QuickBooks mostly displays this error code if problems occur while 
hosting the data file in the multi-user network setup. The potential causes 
for multi-user mode issues in your QB Desktop are mentioned below-

1. QuickBooks hosting settings aren’t appropriate, and workstations running 
in multi-user mode stop you from sharing the data file.
2. The Database Server Manager cannot run due to its background 
processes getting interrupted by the Windows Firewall restrictions or bugs 
on your system.
3. QuickBooks fails to access the company file due to a damaged Windows 
registry or broken file path.
Preventive measures for error H505 in QuickBooks Desktop
QuickBooks won’t let you host the company file and share financial data 
with other users after this error develops. The usable methods to get rid of 
this QB hosting error are discussed below-
Solution 1- Ensure the QB hosting setup is correct before 
hosting the data file
QuickBooks can only share the company file data if the server hosts the file 
in multi-user mode and all the other systems (Workstations) run in single-
user mode to access it. In case your workstations are set to run in multi-user 
mode, you’ll encounter this error and the multi-user network breaks down 
instantly. You can easily counter the error by configuring your QB hosting 
settings as shown in these steps-
1. Launch your QB Desktop application on the system where you encounter 
this error and go to the File menu.
2. Move to the Utilities option and hit the Stop Hosting Multi-user Access 
option.
3. Use these steps on all the workstations to switch them to single-user 
mode and go to the QB File menu on the server computer.
4. Click Utilities and hit the Host multi-user access option.
5. Restart all the systems and open the company file on the server in multi-
user mode.
If the error appears after fixing the hosting settings, move to the next 
solution.
Solution 2- Restart the QB DBSM processes to tackle the minor 
glitches
QuickBooks can also display this error if the Database Server Manager fails 
to run in the background due to minor bugs or glitches interrupting its 
processes. You need to restart the background processes of DBSM to 
prevent the issue from developing again. Use these steps-
1. Press the Ctrl+Shift+Esc to launch the task manager and go to the 
Processes tab.
2. Select all the DBSM processes like QBDBMgrN.exe, QBDBMgr.exe, etc, 
and click the End Task option.
3. Relaunch QB and host your company file.
