Fixing QuickBooks Error Code 6129

QuickBooks error 6129 usually means something is interfering with accessing company files. Whether locally or over your network, several targeted troubleshooting techniques can get your database back online. Follow these key steps to fix error code 6129:

Refresh Network Connection By Renaming Damaged.ND Files

The.ND file extension refers to the network data files facilitating QuickBooks’ access to company files stored on servers. If these become corrupted, all remote connectivity fails with error 6129.

Fortunately, rebuilding fresh network connection configurations is straightforward:

  • Navigate to the folder containing the QuickBooks company files
  • Look for the files with a . ND file extension – the network data configuration files
  • Right-click on the.ND file in question and choose Rename from the menu
  • Append.OLD to the end of the file name and press Enter to rename

This forces QuickBooks to generate an entirely new network data file the next time it looks for a connection.

Rule Out Permissions Issues By Copying Files Locally

Even with valid login credentials, permissions mishaps could be blocking remote or network access in QuickBooks.

Test by copying the problematic company file locally:

  • Create a dedicated folder on your Desktop called QBTest
  • Access the network folder currently housing the inaccessible company file
  • Select the company file and Copy it over into this new QBTest folder
  • Attempt to open up the local copy of the company file

If error 6129 persists on the local version, further diagnosis into connectivity is warranted.
