What is Error 85440?

Error 85440 is a common issue that occurs when Autodesk software is unable to connect to the network license server. This error message indicates that the software cannot find a valid license, preventing you from accessing its features.

Causes of Error 85440

Before diving into the solutions, it's essential to understand the possible causes of error 85440:

  1. License Server Not Running: The license server may not be running or may have stopped functioning, causing the software to lose connection.
  2. Network Connectivity Issues: Poor network connectivity or a faulty network configuration can prevent the software from communicating with the license server.
  3. Firewall or Antivirus Software: Overly restrictive firewall or antivirus settings may block the software's access to the license server.
  4. Incorrect License Server Configuration: The license server configuration may be incorrect or outdated, leading to the error.

Troubleshooting Steps

To resolve error 85440, follow these step-by-step troubleshooting guides:

2. Pros of the Troubleshooting Guide

  • Specific to the Error: It doesn't waste time suggesting a reinstallation of the software (which rarely fixes this specific error). Instead, it focuses on the Network License Manager (NLM) service.
  • Addresses IPv6 Issues: High-quality guides often point out that Autodesk License Manager has historical conflicts with IPv6. Disabling IPv6 on the network adapter is a frequent "hidden gem" solution in these articles that solves the issue when firewall rules look correct.
  • Clear File Paths: Most top results provide exact file paths (e.g., C:\Program Files\Autodesk Network License Manager) to help you locate the necessary files quickly.

Preventing Error 85440: Best Practices

Avoid this error long-term with a few infrastructure changes:

  • ⃝ Centralize licensing on a dedicated VM – Avoid running NLM on a file server or domain controller.
  • ⃝ Install LMTOOLS as a Windows Service – Ensure it restarts automatically after updates/reboots.
  • ⃝ Set static DHCP reservations – Prevent IP changes that break license pathways.
  • ⃝ Configure Group Policy for TCP Keep-Alive – Push this reg key to all CAD workstations: 
    HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\KeepAliveTime = 30000 (DWORD)
  • ⃝ Log and monitor – Use PRTG or SolarWinds to monitor port 2080 availability every minute.

3. Flush DNS & Reset Winsock

Open Command Prompt as Administrator and run:

ipconfig /flushdns
netsh winsock reset
netsh int ip reset

Restart your PC.
