On some platforms, the host ID is derived from the network adapter address.
If the machine where your product is installed or where the license server is hosted has multiple network adapters, running lmutil lmhostid returns one host ID for each network adapter, and returns output similar to this:
The FLEXlm host ID of this machine is ""0013023c8251 0015c507ea90"" Only use ONE from the list of hostids.
If you cannot determine the host ID using the lmutil lmhostid output, use the native operating system commands to get additional details.
