We have a concurrent license and our IT deployed it via server manager before realizing I need it outside our network as well. Is it possible to directly use the license without using the license server?
You can borrow a license if the License Server Administrator has set the borrow capability on the License Manager.
This will allow you to use the license exclusively even though you are not connected to the network.
Please note: you must be connected to the License Manager/network in order to borrow the license initially.
