|Title: Troubleshooting the Network License Manager|
The software is designed to automatically locate the server running on the same subnet, making the setup easier. There are several main reasons why the license server discovery may fail:
As a first step, run the WLMADMIN program (found in the LMTools folder) on the server. If you are unable to see the server name, then the server software itself is not running. Please follow the manual on restarting or re-installing the server software.
There is also a possibility that the server is running, but is being blocked by firewall software on the server (WinXP with Service Pack 2, for example). If this is the case, please try running through Knowledge Base article #269.
If you are unable to see any servers on the subnet you will need to specify the license server by setting an environment variable pointing to server's name or IP address (Rainbow recommends the IP address):
At this point verify connectivity to the server by opening the command line and typing 'PING SERVERNAME'. You should see a reliable response from the server. If you are getting a 'connection timeout' error, please contact your system administrator since this is a problem related to your network. If you are getting a name resolution error, please follow instructions on that below.
If the 'ping' test was successful, please re-run the WLMADMIN utility. If you still do not see the server and features on the left side, the server might be blocked by a firewall, the supplied server name is wrong, or this might be the result of name resolution problems. If the server is showing, but there is a significant delay in displaying feature information, that is also a sign of name resolution problems.
If the server itself is running fine, click on the "+" before the server name on the left and then inspect the features loaded one at a time (the feature status is displayed on the right side). If there are no features available on the left side, contact Carlson Software for the license.
If the server name in the error messages is not what you expected, look below at #3 in name resolution issues.
If there seems to be a significant delay in retrieving the feature information, this may be a result of problems in name resolution. Please refer to instructions below.
If the workstation "freezes" for 10-20 seconds every 5 minutes - you are running an older version of the Sentinel Server software and will need to download and install the new one from knowledgebase article #55. Older licenses are compatible with the new License Manager and will load into it with no problems. Please pickup updated LmTools.zip from same page.
If you are having commuter license problems, please refer to Knowledge Base Article 507 for additional steps which may need to be performed on the workstation by the administrator.
