AutoCAD 2007 network license manager Error 1.5.-15

Starting to use AutoCAD 2007 or other products released this year you might run into this issue. "This situation can occur when you access the license manager through a VPN, dial-up or a slow DSL/ISDN link."

A valid license could not be obtained by the network license manager.

Error [1.5.-15] or Error [1.5.-18]

-15 Cannot connect to license server system. The server (lmgrd) has not been started yet, or the wrong port@host or license file is being used, or the TCP/IP port or host name in the license file has been changed. WindowsXP SP2 platforms have a limit on the number of TCP/IP connection attempts per second that can be made, which your application may have exceeded. Refer to the manufacturer’s documentation on how to change this limit.

-18 License server system does not support this feature.

The solution is in this Autodesk knowledgebase article using FLEXLM_TIMEOUT.

The error 1.5.-15 indicates that the software was unable to find a valid license manager. Common causes of this error message are listed below.

The Autodesk Network License Manager (FlexLM) may not be operational. You should make sure that the license is properly configured and running. Check LMTOOLS > Server Status tab > Perform Status Enquiry. If the license manager is running correctly, this report will list the licenses that are available and the licenses that are in use for each product. If it does not, you should refer to the following solution to make sure that the license manager is configured correctly: Problems configuring the Autodesk Network License Manager (FlexLM).

Make sure that you can ping both from the license manager to the client and from the client to the license manager by hostname. If you are unable to ping by hostname, it indicates a networking problem or an issue with name resolution. Contact your network administrator or IT professional for assistance correcting these problems.

Firewalls and other port filtering software and hardware can block the required license manager traffic. Make sure that port 2080 and the port range 27000-27009 are not being filtered or blocked by any firewalls or network devices. It is strongly recommended that the Windows Firewall be disabled on both the client and license manager machines.

If the license manager is operational, the client machine may not be looking for the correct license manager. Set an environment variable on the client machine to point to the correct license manager. For additional information about setting this environment variable, refer to the following solution: Specifying license servers using the ADSKFLEX_LICENSE_FILE environment variable.

Another tip to improve the performance is to use the IP number of the server instead of the server name.
