Specific Resolution Methods to Fix QuickBooks Error Codes 6000 and 304

This section discusses specific solutions for eliminating error code 6000 304 in QuickBooks depending on whether you access the company file locally or on a network –

Case 1 – You Access the Company Data Files Locally 

If you encounter problems while accessing the company file on your local computer, the following resolution procedure will help you address the issue – 

Solution 1 – Change the Network Data and Transaction Log File Names

Essential configuration files in QB are needed to access the company data files, which include the Network Data and Transaction Log files. But if these files are damaged, you won’t be able to open your company files on the local PC, leading to QB error 6000 304. Thus, you must rename the files by adding to their extensions in the following manner – 

Note: When you rename these configuration files, QB recreates them when scanned with the QB Database Server Manager or when the company file is accessed. 

1. Open the QuickBooks company file folder by going to the location, and then search for the files with the .ND and .TLG extensions but with your company file name. 
2. If you can’t locate these configuration files, check the settings on your Windows OS to ensure hidden files and folders are turned on.
3. Next, right-click each file, choose Rename, add .OLD at the end of the file name, and hit Enter to give effect to the name changes.

Once done, you must rerun QuickBooks on the local PC and check the status of the company file access error. If QuickBooks error code 6000 304 persists, follow the instructions in the next solution to rectify it. 

Solution 2 – Try Accessing a Sample File 

The company file access issues can be a result of damage in the file or the QB Desktop application. To figure out the underlying issues, you must access a sample file in QBDT using the prompts below – 

1. Go to the No Company Open window in QB Desktop, then select Open a Sample File to proceed.
2. Now, a list of sample files will emerge on your screen; choose any one and check if it opens without issues. 

If the sample file opens, your current company file is damaged (run QB File Doctor as mentioned above), or the file location/folder is corrupted (see Solution 4 below). 

On the contrary, if the sample file is inaccessible, your QB program might be damaged and needs to be repaired (see the next solution). 

Solution 3 – Repair QuickBooks Desktop 

The next solution is to use the specific utilities in QB Tool Hub and repair the QBDT program. This is because company file access errors in QB can arise if the program is damaged, corrupted, or improperly installed. 

1. Open the QB Tool Hub, then from the Program Problems tab, select the Quick Fix My Program tool, and initiate a program repair procedure.
   
2. After the tool stops, rerun QB and check if you can access the company file; if not, move to the Installation Issues section.
3. Finally, select the QuickBooks Install Diagnostic Tool to scan and fix the installation problems in QBDT and restart QB once the process is over.
   

Now, try accessing the company file again, but if QuickBooks error 6000 304 persists, follow the next resolution step to resolve it. 

Solution 4 – Move the Company File to a New Location 

As mentioned in Solution 2 above, if the sample file opens, either the current company file or the file folder is damaged. If repairing the company file using QB File Doctor doesn’t help fix the error, there is a possibility that your current file location is corrupted. To fix this scenario, you can try moving the company file to a new location and accessing it from there as follows – 

1. Locate the company file from the original file location, right-click on the file, and click Copy.
2. Right-click on an empty space on your desktop, then click Paste and hold the Ctrl key.
3. Further, open QuickBooks to access the No Company Open tab, select Open or Restore an Existing Company, and access it.

If the file opens from the new location, the original folder might be damaged, or the file is in multiple folders.

However, if the file doesn’t open from the new location, move to the next solution to restore the file back up as the next resolution.

Solution 5 – Restore the Company File Backup Version

Another solution to eliminate QuickBooks company file error 6000 304 is to restore the company file backup version using the instructions below – 

1. Firstly, save the backup version on the local hard drive, then reopen QuickBooks and move to the File section.
2. Select Open or Restore Company, click Restore a Backup Copy, hit Next, and browse your PC for the backup file version.
3. The file will have your company file name but with the .QBB extension; once found, pick a folder to save the restored version and click Open.
4. Next, hit Save, then save the file in a distinct folder from the original company file to avoid confusion and ensure you don’t overwrite any data unless you are sure you want to. 

Once done, reopen QuickBooks and try accessing your company file to check the status of the error message. If QuickBooks error 6000 304 persists, follow the next solution to recover the damaged file with the ADR tool.

Solution 6 – Recover the Damage Data with the ADR Feature

If the company file cannot be repaired and restoring the backup version doesn’t help, the next alternative is to use the ADR tool. The Auto Data Recovery feature in QuickBooks helps recover lost or damaged data using the company file and the Transaction log file. 

You can follow the extensive process of recovering the damaged data using QuickBooks Auto Data Recovery and then rerun QuickBooks Desktop. Sign in to your company file and try to access it to ensure the 6000 series error is successfully dismissed. 

Case 2 – You Access the QB Company File Over a Network

If you are unable to open or access your QuickBooks Desktop company file over a network or a multi-user environment, then proceed with the following troubleshooting process to fix the error – 

Solution 1 – Disable Hosting on All Workstations

While running QuickBooks in multi-user mode, the correct way is to use a single PC to host the company file. If hosting is enabled on multiple workstations, you must disable the hosting mode using the instructions mentioned below –

1. Start by accessing the Product information screen (press F2), then find the Local Server Information and check the hosting.
2. Ensure it is turned off on all the workstations; if not, move to the File menu and select the Stop Hosting Multi-User Access option from the Utilities tab.
   

Once hosting is disabled on all the workstations save for the host PC, try accessing your company file to check the error’s status. If QuickBooks Desktop error 6000 304 keeps appearing, follow the detailed steps in the next solution to eliminate it. 

Solution 2 – Use QuickBooks Database Server Manager

Before following this solution, you must ensure that you rename the Network Data and Transaction Log files by following Solution 1 from ‘Case 1: You Access the Company File Locally’ above. Once the files are renamed, you must run a scan using the QB Database Manager in the following manner – 

1. Select the Network Issues section of the QuickBooks Tool Hub, then click QuickBooks Database Server Manager and ensure QuickBooks is installed on the server PC.
   
2. In QB Database Server Manager, select Start Scan, browse to the company file location, and run the file scan process. 

Once done, reopen QuickBooks and access your file to ensure the error is resolved; otherwise, move to the next solution. 

Solution 3 – Terminate the QuickBooks Desktop .EXE Processes 

Try terminating all the QuickBooks processes ending with the .EXE extension before reopening your company files in the following manner – 

1. Sign in as an admin on your server PC, then press Ctrl + Shift + Esc and access the Windows Task Manager.
2. Next, check all the user processes, click the Users tab, and right-click each QB process (like QBW32.exe).
3. Finally, click the End Task button, and once all the .exe processes are terminated, rerun QB Desktop.

Now, try accessing your QB company file over the network again to check the status of the error code. If QuickBooks error 6000, 304 continues to appear, follow the next resolution step to terminate it. 

Solution 4 – Access a Sample File to Check for Underlying Issues 

Follow the steps mentioned in Solution 2 of ‘Case 1: You Access the Company File Locally’ above to access a sample file, and based on the results, take the following resolution steps – 

1. If the sample file opens, fix the current company file damage using QB File Doctor. If that doesn’t work, move the file to another location before accessing it (see Solution 4 of ‘Case 1: You Access the Company File Locally’). 
2. If the sample file doesn’t open, repair QuickBooks from the QB Tool Hub (see Solution 3 of ‘Case 1: You Access the Company File Locally’). 

Once done, if you still encounter the same company file access error, proceed to the next solution to troubleshoot it. 

Solution 5 – Configure the Firewall Settings

If the Windows firewall settings are incorrectly configured, they can block QuickBooks and restrict users from accessing their company files in a multi-user environment. To fix this issue, users must reconfigure the Windows firewall settings and remove the restrictions imposed on QBDT.

Once the settings are changed, rerun the app to check the status of QuickBooks error 6000 304, but if it persists, move to the next resolution step.

Solution 6 – Check the Folder Sharing Permissions in QB

If there are inadequate permissions to share the company file in QuickBooks multi-user mode, QuickBooks error 6000 304 is bound to occur. To eliminate this error code, you must review the folder-sharing permissions and set the permission settings correctly using the detailed instructions below –

Folder Permissions for QBDataServiceUser
