### Steps to Fix the Issue
To resolve the QuickBooks Enterprise multi-user mode not working problem, follow these detailed steps:
### Step 1: Check Hosting Settings
1. Open QuickBooks on each workstation.
1. Go to File > Utilities.
1. If you see "Host Multi-User Access," do not select it. This means hosting is not enabled on that workstation, which is correct. Ensure hosting is only enabled on the server.
1. On the server, ensure "Host Multi-User Access" is enabled.

### Step 2: Verify the .ND and .TLG Files
The .ND (Network Data) and .TLG (Transaction Log) files are crucial for multi-user functionality.

1. Navigate to the folder containing the company file.
1. Look for files with extensions .ND and .TLG. For example, if your company file is "CompanyFile.QBW," you should see "CompanyFile.ND" and "CompanyFile.TLG."
1. Right-click these files and select Rename, then add ".old" to the end. For example, "CompanyFile.ND" becomes "CompanyFile.ND.old."
1. Open QuickBooks and rescan the folder using QuickBooks Database Server Manager (see Step 5).

### Step 3: Adjust Firewall and Antivirus Settings
Firewalls and antivirus software often block QuickBooks processes. To resolve this:

1. Add QuickBooks as an exception in your firewall and antivirus software.
1. Open the control panel of your firewall/antivirus.
1. Add exceptions for QuickBooks programs (QBW32.exe, QBDBMgrN.exe, QBServerUtilityMgr.exe).
1. Restart your computer and check if the issue persists.

#### Step 4: Ensure Folder Permissions Are Correct
1. Right-click the folder containing the company file.
1. Select Properties > Security tab.
1. Ensure all users have Full Control permissions.
1. Click Apply and then OK to save changes.

#### Step 5: Use QuickBooks Database Server Manager
1. Open the QuickBooks Database Server Manager on your server computer.
1. Go to the Start menu, type "Database Server Manager," and open it.
1. Click Add Folder and navigate to the folder containing the company file.
1. Click Scan.
1. After scanning, check the status to ensure the company file is ready for multi-user mode.
