Host and user not pairing

Let's perform some troubleshooting steps for QuickBooks multi-user mode to work, Con56.

Generally, there are several reasons why hosting and user aren't pairing. I've outlined them in bullets below:

• QuickBooks is not installed on the server.
• Possibly that the hosting settings are not properly configured.
• Firewall or antivirus software is not allowing communication between user computers.
• The database server is unable to open the company file.
• Windows file permissions are not properly set.
  
  

Also, since you've just changed your network, you'll have to set up again the multi-user mode in QuickBooks Desktop. 

We can check the folder permissions on your server computer to ensure that the folder holding your company files has permission to be on your network. If so, make sure that the QuickBooks Database Server Manager is installed on your server computer. This way, your company files will be shared with other computers over your network. Then, set the Windows admin rights. This will let you change your firewall settings and folder permissions. Next, scan your folder using the Database Server Manager to access your file over the network.

Lastly, turn on hosting on your server computer:

1. Go to the File menu and hover over Utilities.
2. Select Host Multi-User Access. Then click Yes to confirm.

However, if you're using another solution like Enterprise Hosting through Right Networks or one of our affiliation Intuit Hosting Providers, you can contact them directly to restart your hosting environment and work with them as you troubleshoot.
