2.2 Firewall and Port Blocking

• Autodesk license managers use port 2080 (default for lmgrd) and a dynamic vendor daemon port (often 27000-27009). Windows Defender Firewall or corporate security software may block these.

Step 5: Examine the License Log for Error 8.544.0 Clues

Open the license log file (e.g., C:\Autodesk\licenses\license.log). Look for entries like: Part 1: Understanding Error 8

15:23:01 (adskflex) DENIED: "74000REVIT_2025_0F" user@workstation (Invalid license file syntax. (-8.544))

This confirms the server is rejecting the request specifically with Error 8.544.0, often due to a mismatch between the license file and the requested feature.

On the License Server:

• Allow Inbound Rules for:
  • lmgrd.exe (TCP ports 2080 and dynamic)
  • adskflex.exe (TCP on the vendor port)
• If using Windows Firewall, add:

  netsh advfirewall firewall add rule name="Autodesk LMGRD" dir=in action=allow program="C:\Autodesk\Network License Manager\lmgrd.exe" enable=yes
