QuickBooks Error 557 often appears when critical program files become corrupted. But did you know network problems can also cause this error? For multi-user setups, addressing network conflicts is key to troubleshooting Error 557.
This guide will cover networking tips and best practices to eliminate Error 557 in QuickBooks.
What are the Cause of QuickBooks Error 557?
First, a quick recap on the source of Error 557. This error indicates damaged component files with an.ND, TLG, or.OSD file extension. These contain programming code and preferences that QuickBooks needs to function.
If just one file gets corrupted, you'll see "QuickBooks Error Code 557" when attempting to open the software.
How Networking Problems Can Cause QuickBooks Error 557
Here's the connection between networking and Error 557:
For multi-user environments, QuickBooks component files reside on the host computer. All other machines access them over the network.
But if connection problems like lag or timeouts exist, remote machines may fail to read these components from the host properly. This can corrupt the files and trigger Error 557 the next time QuickBooks opens.
So, networking problems can indirectly cause the damaged components behind Error 557.
Step 1: Check Your Internet Connection
Start troubleshooting with your connection if you're accessing QuickBooks remotely over the Internet.
• Reset the router and modem to refresh the connection.
• Ensure your ISP service is running properly.
• Check for cable damage, low signal, or hardware issues.
An unstable Internet link between locations can damage components and Error 557.
Step 2: Verify Host Accessibility
If using QuickBooks multi-user in an office, test connectivity to the host computer:
• Ping the host PC from remote machines to check for network availability.
• Scan host ports to ensure traffic on port 8019 is open.
• Confirm remote machines have proper permissions to access the host.
• Disable firewalls temporarily to isolate software conflicts.
Verifying seamless access to the host prevents timeouts that corrupt components.
Step 3: Update QuickBooks and QB Database Manager
Outdated versions of QuickBooks and the QuickBooks Database Manager can also cause network conflicts, resulting in Error 557.
Run updates on both the host and remote machines:
• Host: Update QuickBooks and Database Manager to the latest.
• Remote: Update QuickBooks to match the host version.
Mismatched versions lead to sync errors that damage component files. Keeping software updated avoids this.
Step 4: Review Multi-user Mode Settings
Double-check preferences to optimize multi-user performance:
• Switch to single-user mode on all machines before switching back to multi-user.
• Set multi-user mode to use TCP/IP networking.
• Enable communication over port 8019.
• Increase connection timeout duration.
Tweaking preferences can resolve networking delays and bottlenecks leading to Error 557.
