After rebooting TMS server, an error prompts and says that the license file is not right. Check the ESN and find that it is not the same as that used to apply for the license file.
The license file is wron, please load right license file.
Disable or disconnect the wrong network card and reboot the server, then the problem will be fixed.
This server has two network cards and both are connected to the network. Every time it powers on, the ESN will be calculated based on the MAC of the first enabled network cards. So, if the network card, bonded to the ESN used to apply for the license file, is enabled later then the other, the ESN will change and the license file is not valid any more.
