Troubleshooting Problems ❚❘❘ Configure TCP/IP before proceeding, then follow the steps in Configuring the FLEXlm Server. The AdLM runs diagnostics and then goes online. The diagnostics may take as long as three minutes to run. When the network version of combustion is started on a workstation, combustion responds by first sending a broadcast to the local network segment to look for a license server with a free combustion license. If a license server is found, a license is checked out from the server, and combustion will start on the workstation. If a license server resides in a different network segment from the workstation, the license server will not be found unless the ACADSERVER environment variable is set to include the license server's hostname on each combustion workstation. A workstation may be restricted to pulling licenses from specific license servers by the prefix symbol @ to the hostname listed in the ACADSERVER value. Using the @ symbol effectively disables the broadcast method of finding a license server. Following are potential problems that can occur and their solutions: • The License Manager Service does not start. Cause Solution The AdLM is run on the wrong platform. The AdLM requires Windows 2000 or Windows NT running on an AMD or Intel-compatible processor running 300 MHz or higher. Microsoft TCP/IP is not installed or is improperly configured. The AdLM requires TCP/IP to operate. Verify the TCP/IP configuration by using the PING command at a DOS command prompt. The AdLM was not Start lmtools.exe, go to the Start/Stop/ launched from Reread tab, and press "Start server". the Start/ Stop/ Reread panel of lmtools.exe. • AdLM will not issue licenses for three minutes after startup. Cause Solution The default diag- This is normal operation.

If you cannot successfully "ping" the license server from a combustion workstation and "ping" the workstation from the license server, the AdLM will not work. Name resolution may be accomplished in a variety of ways on a Microsoft TCP/ IP network. The simplest method to provide name resolution is to create a hosts file with entries for all workstations on the network, and copy it to the \winnt\system32\drivers\etc folder on Windows 2000 and NT systems. Windows 2000 and Windows NT come with a sample hosts file located in the proper destination folder for that operating system. The system date and time are incorrect. Verify that the date and time are correct on all workstations, and that they are synchronized with the AdLM station. The AdLM will not issue a license to a workstation that has an invalid date. The license server Set the ACADSERVER environment vari- is in a different able value to contain the hostname of subnet from the the license server so that combustion workstation. can connect to a license server on another subnet. To set ACADSERVER to multiple license servers, separate each hostname with a semicolon. Consult your operating system documentation on how to properly set an environment variable. The value of an environment variable can be confirmed by typing set |more at a DOS command prompt. 31
