What is QuickBooks Error 6175?

QuickBooks Error 6175 typically occurs when the QuickBooks Database Server Manager is unable to start or respond while you attempt to access the company file from a different system in a multi-user environment.

You might see an error message like this:

"QuickBooks is attempting to open this company file. Please wait."
Or
"Error code 6175: QuickBooks is unable to access the company file."

This issue often arises in setups where one computer hosts the file, and others try to access it across a network.

What Causes QuickBooks Error 6175?

Several factors could be triggering this error. The most common include:

• QuickBooks Database Server Manager is not running or blocked

• Hosting settings are configured incorrectly

• Firewall or security software is blocking QuickBooks

• Damaged or corrupted company files

• Server is too busy to respond to a request from the workstation

• The Database Server Manager lacks Windows admin privileges

How to Fix QuickBooks Error 6175: Step-by-Step

Here are the best ways to troubleshoot and fix QuickBooks Error 6175.

Fix 1: Verify Hosting Settings

Make sure only the server computer is set to host the company file.

1. Open QuickBooks on each workstation.

2. Go to File > Utilities.

3. If you see Stop Hosting Multi-User Access, click it.

4. On the server, hosting should remain enabled.

Fix 2: Restart QuickBooks Database Server Manager

1. Press Windows + R, type services.msc, and hit Enter.

2. Find and right-click on QuickBooksDBXX (XX represents your QuickBooks version, like QuickBooksDB30 for 2020).

3. Choose Restart.

4. After restarting the service, try accessing your company file again.

Fix 3: Run QuickBooks File Doctor

1. Download and install the QuickBooks Tool Hub.

2. Open the Tool Hub and click Company File Issues.

3. Select Run QuickBooks File Doctor.

4. Choose your company file and run a full scan to fix issues.

Fix 4: Adjust Firewall and Antivirus Settings

Make sure QuickBooks and Database Server Manager are allowed through your firewall.

1. Open Control Panel > System and Security > Windows Defender Firewall.

2. Click Allow an app or feature through Windows Defender Firewall.

3. Ensure QuickBooks and QBDBMgrN.exe are allowed on both private and public networks.

4. If using third-party antivirus software, add QuickBooks to the exception list.

Fix 5: Switch to Local Access (Temporarily)

If you're unable to access the file over the network:

1. Move the company file to your local drive (e.g., Desktop).

2. Open it from there to check if the file is the issue or the network.

3. If it opens fine, the issue lies in the network configuration, not the file itself.

Fix 6: Grant Windows Admin Rights

Sometimes QuickBooks Database Server Manager doesn’t have enough permission.

1. Press Windows + R, type services.msc, and press Enter.

2. Find QuickBooksDBXX, right-click > Properties.

3. Go to the Log On tab.

4. Choose This account and enter admin credentials.

5. Apply and restart the service.
