Why does the License Manager go down when user disconnects from Internet?
The customer's license server is a laptop. The license is tied to the disk serial number.
Whenever the user disconnects from the Internet, the ANSYS license manager goes down.
The ANSYS exe is connected to the socket through the IP address that was used when user originally started the ANSYS run.
This is why they require a static IP address for license servers.
To resolve this issue, have the user specify the license server using the loopback adaptor IP (firstname.lastname@example.org)
instead of the host name in the ansyslmd.ini file, leaving the host name in the license.dat file as is.
