Since a borrowed SolidNetWork license is removed from the pool of available licenses, that borrowed license must be returned for it to become available again.
In the License Usage tab, you can also view the number of Total
licenses.
You
do not need to return licenses after the expiration date. The license is
returned to the pool on the SolidNetWork License Manager at midnight on the expiration date
and the applications on the remote system no longer run.
