Step-by-Step Guide to Solve the QuickBooks Multi-User Hosting Error H505
If you see the error code H505, one of the workstations is set to be the server for QuickBooks. Your server computer must be the one that is hosting the company files and is set to host multi-user mode.
On the workstations, the Host Multi-User Access option should be disabled. The workstations are the computers that do not host the company file over a network. They are connected to the server computer and accessing the files hosted by it.
Method 1: Configuring hosting settings
Open QuickBooks on any workstation where the error code H505 occurs.
You don’t need to open the company file.
But go to the File menu.
Choose Utilities, and if you see the Host Multi-User Access option, you don’t need to tap it. Instead, go to the next workstation because one is not creating a nuisance.
If you see the Stop Hosting Multi-User Access option, you need to select it.
You need to follow all the above steps on all the workstations where you are encountering the error.
After you have checked all the workstations, you also need to look at the server computer.
Open QB on the server computer.
Next, you need to go to the File menu.
Choose Utilities.
If the Host Multi-User Access option is an option, choose it.
On the other hand, if you see the Stop Hosting Multi-User Access, don’t select it.
Method 2: Rename the network descriptor file
Go to the folder with your company files and look for .ND.
When you don’t find .ND files, open a company file to create them.
Next, you need to right-click on each .ND file and rename it. Don’t forget to add .old at the end of the file name.
Open QB Database Server Manager.
Scan the folders to create new .ND files again.
