A closing comment on this thread,
To be able to borrow a NX license, your license file must have the "borrow feature", ( which not all license files has.) This feature is to my knowledge free but must exist in the license file.
NX 3(?) - NX8.5 : ( I assume that borrowing was added in NX3) NX 9 the dialog is different, i have yet no experience of how it works but it should be similar.
If the borrowing feature exists , in the Start - programs - Siemens NX x.x - NX Licensing tools - license options : there is a tab named "borrowing" , If the feature doesn't exist in the license file , there is no such tab.
When borrowing, have the borrowing computer connected to the network such that you can run NX.
Start the NX license options ,select the borrowing tab, set return date, select what licenses to borrow, press the "borrow licenses button".
Note that while this license is borrowed, it is not available for other users on the same license server. If you are multiple users on the same license server and one user is about to travel, do not borrow unique licenses unless there is a need for it during travel.
Restart the laptop that is going to travel , disconnect the network ( and wireless) , Start NX and verify that it runs as expected. ( try the different options
If you return early from traveling there is an option to return borrowed licenses ( in the same tab/ dialog) Else the borrowed licenses will be locked to that laptop until the borrowing period expires.

Tomas
