Resolve error H202 or other multi-user errors when opening QuickBooks Desktop over a network by editing the Windows hosts file.
|This solution is intended to be used as a workaround to bypass broken Domain Name Settings (DNS) within Windows. If you are not comfortable with these steps or have questions relating to DNS settings, Intuit recommends you to contact a qualified IT professional or refer to Microsoft article.|
To perform the following steps, you need Administrator access to the server and any computers connected to the server. It is recommended to have a pen/paper handy to write down the required information as you may be going back and forth to computers.
Step 1: Find the IP address and computer name of the server and workstation
Follow these steps for the server and any computer/workstation connected to the server.
- On the server, press Windows + R to open the Run window.
- Type cmd and press Enter to open a Command Prompt window.
- Type ipconfig /all (there is a space after ipconfig) and press Enter.
- Take note of the Host Name (computer name) and the IP Address (it will either be IP Address or IP Address v4).
- Repeat steps 1-4 on any additional computer connected to the server.
Step 2: Edit the Windows hosts file
Important: Hosts files deal with STATIC IP addresses. If the network is using DYNAMIC addressing, this could cause problems if the server is rebooted & obtains a different IP address then configured in the HOSTS file. The Windows server should be configured to maintain the same address for the network at all times.
- Close QuickBooks.
- On the Server, select the Start menu and then Computer.
- Then go to either:
- Double-click the hosts file.
- Choose Notepad if you are asked to select a program to open with.
- Enter the IP address followed by Computer Name. The Server will have workstation IP and computer name while Workstation will have Server IP and computer name. When entering this information, use the Tab key instead of the space bar to separate the IP address and computer name. See the image below:
After completing steps 1 and 2, open QuickBooks in multi-user mode.
