VPN-Specific Solutions

Option A: Use a VPN that supports NetBIOS over TCP/IP Many VPNs (Cisco AnyConnect, OpenVPN) block broadcast traffic. Ensure your VPN profile allows:

• NetBIOS name resolution
• WINS server forwarding

Option B: Deploy a license server in the cloud Autodesk allows NLM on AWS, Azure, or Google Cloud. Place the server inside the same VPC as your remote access VPN endpoint.

Option C: Edit the HOSTS file (last resort) On remote laptops, edit C:\Windows\System32\drivers\etc\hosts as Administrator. Add:

192.168.1.100   license-server.mycompany.com

Quick checklist (run in this order)

1. Confirm other users — Are others affected? If yes, likely server-side; if only you, likely client-side.
2. Check license server service — On the server, ensure the Autodesk License Manager (FlexNet) or NLM service is running.
3. Verify server reachability — From the client, ping the server name/IP and test port (typically 2080 or 27000–27009 range).
4. Confirm license count & expiration — Inspect the license file or use lmtools/Autodesk Network License Manager diagnostics to confirm available seats and expiry.
5. Check client license configuration — Confirm client points to correct server hostname/IP (via ADSKFLEX_LICENSE_FILE, LM_LICENSE_FILE, or product’s network settings).
6. Match product and license versions — Older license servers may need an update to serve newer product releases.
7. Examine error/log files — Review client log and server debug logs (lmgrd/debug.log) for precise rejection reasons.
8. Restart services/clients — Restart the license server service and affected client machines after configuration changes.

Solution 1: Check License Server Status

1. Ensure the license server software is running on the server machine.
2. Check the license server logs for any errors or issues.
3. Verify that the license server is properly configured and licensed.

Fix 4: Reset the Autodesk Licensing Components

Sometimes the local licensing middleware corrupts.

1. Close all Autodesk products.
2. Delete the contents of C:\ProgramData\FLEXnet (backup adskflex_* files if needed).
3. Delete C:\ProgramData\Autodesk\CLM\LGS\*.LIC
4. Open Registry Editor (regedit) and navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\FlexLM License Manager
   • Delete any ADSKFLEX_LICENSE_FILE values (they will be recreated).
5. Re-launch Autodesk product and re-enter the license server hostname.
