Issue Details

If my network is down, having connectivity issues, or NI Volume License Manager (VLM) is temporarily inaccessible or unavailable for other reasons how are software end users of affected?


If your volume license server is inaccessible for any reason, there are different symptoms that will occur, depending on the license type users are using:

Non-Concurrent Licenses
End users using non-concurrent licenses who have successfully launched the software before the VLM becomes inacceessible will automatically receive an evaluation license for the product. This evaluation license will be valid for 14 days from the point it is generated. The 14 day period is intended to give customers enough time to troubleshoot and repair the server connection. After the connection to the server is reestablished and software is successfully launched, the 14 day evaluation license will be restored in case the server is inaccessible in the future.
Concurrent Licenses
End users using concurrent licenses will not be able to access their software until a successful connection to the VLM server is reestablished.

Disconnected Licenses
If end users need a computer to be disconnected from the network, administrators can create a disconnected license file for that computer.
