Verify that SentinelLM is running on the server as a process or a service. If it is not currently running, open a Windows Explorer and browse to the C:\Idsnet\ folder on the server. To run SentinelLM as a process, double-click lservnt.exe; as a service, double-click loadls.bat and then verify the service is running and set to AUTOMATIC.

Once SentinelLM is running, run WLMAdmin.exe from the server. In WLMAdmin.exe select View >> All in Subnet from the pull-down menus. Verify that it returns a server with valid licenses. Close WLMAdmin.exe if the correct number of licenses is shown. If there are no licenses or an incorrect number of licenses shown, make a copy of the FCNLOLIC.txt file located in the same directory and then rename it to FCNLOLICbak.txt. Run ECHOID.exe; which will create a new FCNLOLIC.txt. Then open the new FCNLOLIC.txt and FCNLOLICbak.txt to compare them.  If any of the lines after 2-XXXX are different, you will have to redo the NLO Installation.

If all the entries are the same, go to the client machine. First, verify that the server is visible from the client machine. If the server is able to be seen from the client, do the following:

1. Right-click My Computer, and then click Properties
2. Click the Advanced tab
3. Click Environment variables
4. Click New for System Variable

The variable name should be LSFORCEHOST, and the variable value should be the name or the IP address of the server. Using the IP address value could possibly result in faster license detection because of the lack of a DNS lookup, however it is rarely ever a noticeable difference. After this step, launch FlexCAD to verify the client machine is seeing the license. 

After the previous steps have been complete, if the license is still not seen by the client machine, verify that the server isn't on a different subnet than the client machine. If they are on different subnets, make sure to add the server-name to the client's windows host file.

Windows XP
c:\windows\system32\drivers\etc\hosts

Windows NT/2000
c:\winnt\system32\drivers\etc\hosts

In this file, a line will need to be added with: [IP Address] [tab] [Host Name]

If the client machine still cannot find the correct license file, try to ping the IP address or server name of the license server. If the ping cannot find the server then there is a network configuration problem that must be resolved by your IT department.

If the IP address returns a successful ping but not the server name then there is a problem with network domain name resolution. To resolve this, either make sure all references to the license server use the IP address, or have your IT department check the domain name server being used.
