QuickBooks Multi-User Mode allows multiple users to work simultaneously on the same company file from different systems. A multi-user issue occurs when this functionality fails — locking access, disconnecting users, or showing error messages such as: “Error H202: QuickBooks cannot connect to the company file.” “Only the host computer can access the file.” “You are in single-user mode.” These messages typically appear when QuickBooks cannot establish a proper connection between the host system and the networked workstations. 🛑Why Does QuickBooks Multi-User Mode Stop Working? Several technical issues could trigger a multi-user connectivity breakdown: 🔌1. Hosting Misconfiguration Only the server/host system should have hosting enabled. If workstations also try to host, it creates a conflict. 🌐2. Network Issues or Improper DNS Settings If systems are on different networks or DNS isn't resolving the host computer name properly, QuickBooks can’t find the company file. 🔥3. Firewall or Antivirus Blocking QuickBooks Security software can block ports or QuickBooks processes needed for multi-user communication. 📂4. Database Server Manager Not Running QuickBooks relies on the Database Server Manager to allow multi-user access. If it’s not running, users get locked out. ⚙️5. Damaged or Incompatible .ND Files The .ND (Network Data) file allows access to a company file over a network. If this file is corrupted or missing, the connection fails. 🛠️How to Fix QuickBooks Multi-User Mode Not Working – Complete Guide ✅Solution 1: Verify Hosting Configuration On all workstations, open QuickBooks > Press F2. At the bottom, check Local Server Information > Hosting. Make sure hosting is disabled on all workstations and enabled only on the host computer. 📞Not sure which PC should host? Call +1-800-223-1608 or +1800.223.1608 for guided help. ✅Solution 2: Use QuickBooks Database Server Manager Install Database Server Manager on your server (available in the QuickBooks Tool Hub). Open Tool Hub > Network Issues > QuickBooks Database Server Manager. Browse to your company file folder and scan it. This recreates a new .ND file and ensures the database server is running. ✅Solution 3: Restart QuickBooks Services On your server computer, press Windows + R, type services.msc.

Type ping [ServerName] and press Enter. If the ping fails, there is a network-level issue preventing communication. 📞Need help with server-to-workstation setup?

Locate the corresponding .ND file (e.g., CompanyFile.qbw.nd). Right-click > Rename > Add .old at the end. Open QuickBooks and re-scan the folder via Database Server Manager. ✅Solution 7: Enable Folder Sharing Permissions Ensure the folder with your company file is shared and has full read/write permissions.

A: It means QuickBooks can’t reach the server where the company file is stored. It’s a common multi-user access error. Q3: Can I use QuickBooks in multi-user mode over Wi-Fi? A: It’s not recommended.
