This error is part of the H-series errors, which usually relate to hosting and multi-user setup issues.
Common Causes of QuickBooks Error H303
Several factors can trigger QuickBooks Error H303, including:

QuickBooks Services Not Running: Necessary QuickBooks services, such as QuickBooksDBXX or QBCFMonitorService, might not be running.
Network Issues: Problems with the network, such as incorrect DNS settings or a weak network connection, can lead to this error.

1. Verify Hosting Settings
Ensure that the hosting settings are configured correctly on both the server and workstations.

Ensure that "Host Multi-User Access" is selected. If it says "Stop Hosting Multi-User Access," do not select it.
On Workstations:
Open QuickBooks on each workstation.
Go to "File" > "Utilities".
Ensure that "Stop Hosting Multi-User Access" is selected.
2. Use the QuickBooks File Doctor Tool
The QuickBooks File Doctor Tool can help diagnose and fix network issues.

Retry Accessing the Company File: Once the tool completes its process, try opening the company file again.
3. Check Firewall and Security Settings
Ensure that your firewall or security software is not blocking QuickBooks.
Add Firewall Exceptions:
Open your firewall settings.
Add exceptions for QuickBooks programs (e.g., QBW32.exe, QBDBMgrN.exe, QBCFMonitorService.exe).
Ensure that ports 8019, 56728, 55378-55382 are open.
Configure Security Software:
If you have antivirus software, add QuickBooks as an exception or temporarily disable the software and check if the error is resolved.
4. Rename the .ND and .TLG Files
Renaming the .ND and .TLG files can help resolve configuration issues.
Locate the Files:
Navigate to the folder where your company file is stored.
Find the files with the same name as your company file but with .ND and .TLG extensions (e.g., companyfile.qbw.ND and companyfile.qbw.TLG).
Rename the Files:
Right-click each file and select "Rename".
Add ".old" at the end of each file name (e.g., companyfile.qbw.ND.old).
Retry Opening QuickBooks:
Open QuickBooks and try accessing your company file again. New .ND and .TLG files will be created automatically.
5. Restart QuickBooks Services
Ensure that necessary QuickBooks services are running.
Open Services:
Press Windows + R to open the Run dialog box.
Type "services.msc" and press Enter.
Locate QuickBooks Services:
Find QuickBooksDBXX (where XX is the version number) and QBCFMonitorService.
Right-click each service and select "Restart".
Retry Accessing the Company File:
Open QuickBooks and try accessing your company file again.
6. Check Network Configuration
Ensure that your network settings are configured correctly.
Verify DNS Settings:
Open the Command Prompt.
Type "ipconfig /all" and press Enter.
Ensure that the DNS settings are correct for your network.
Check Network Connection:
Ensure that all computers are connected to the same network.
Verify that there are no network interruptions or weak connections.
7. Create a New Folder for the Company File
Creating a new folder and moving the company file can sometimes resolve access issues.
