What are the steps to fix QuickBooks Error “6000, 305”?

There are multiple ways to fix this error. You should apply these methods in a sequential order—from basic to advanced—based on the setup (single-user or multi-user).

Solution 1: Rename .ND and .TLG files

QuickBooks uses .ND and .TLG configuration files to access company data. Corrupted versions of these files can trigger error 6000, 305.

Steps:

1. Open the folder where your company file is stored.
2. Locate files with the same name as your company file but with extensions .ND and .TLG.

4. Reopen QuickBooks and try accessing the company file again.

Solution 2: Move the company file to a different location

Changing the file location helps isolate access problems caused by a damaged folder or restricted permissions.

Steps:

1. Create a new folder on your desktop.
2. Copy your company file (.QBW) and paste it into the new folder.
3. Open QuickBooks and select Open or restore an existing company.
4. Browse to the new location and try opening the file.

Solution 3: Turn off hosting on all workstations

Steps:

1. Open QuickBooks on all workstations except the server.
2. Go to File > Utilities.
3. If you see “Stop Hosting Multi-User Access,” click it.
4. Repeat for all workstations.
