Follow the methods below to help you troubleshoot the issue and eventually fix error code H101, H202, H505 or H103 whenever you’re getting one.

Run QuickBooks File Doctor

Using the QuickBooks File Doctor is one possible way to resolve the QuickBooks issues H101, H202, H103, or H505. A diagnostic tool called the QuickBooks File Doctor can assist in locating and fixing network problems that lead to QuickBooks difficulties. 

  1. To run QuickBooks File Doctor, first, download and install the QuickBooks Tool Hub, a collection of all the necessary tools needed to fix common QuickBooks errors. 
  2. Once installed, open the QuickBooks Tool Hub, select the Company File Issues tab on the left-hand side, and click the Run File QuickBooks Doctor button to start the utility. 
  3. Wait for it to finish and see if that resolves the problem.

Check QuickBooksDBXX Service

It may indicate that the QuickBooks Database Server Manager (QBDSM) is not installed on the server if the QuickBooksDBXX Service is not visible. 

  1. Run Database Server Management and make sure the QuickBooksDBXX Service is displayed to see if QBDSM is installed. 
  2. Make that the QuickBooksDBXX Service is functioning and visible if you want to use QuickBooks in multi-user mode. 
  3. Moreover, make sure QuickBooks has hosting turned on so that users may view the company file in multi-user mode.

Modify Host File

Host file is a plain text file that converts hostnames to IP addresses. 

  1. Open the “Run window” by simultaneously hitting “Windows + R” to begin editing the host file. 
  2. The Command Prompt will then appear once you input “cmd” and “Enter.” 
  3. The command “ipconfig/all” must then be entered and the enter key pressed. This will reveal your server’s IP address. The IP address must then be copied and added to the host file.

Checking Your Hosting and Services

This fix entails quitting and starting QuickBooks’ multi-user hosting. 

  1. Launch QuickBooks and choose File > Utilities > Stop Hosting Multiple User Access from the menu. 
  2. This will make QuickBooks no longer host multiple user access. 
  3. To enable hosting, select File > Utilities > Host Multi-User Access. 
  4. Restart QuickBooks on each workstation once again. 

This will guarantee that all workstations can access the company file and that QuickBooks is hosting multi-user access.
