License/Hardware Key for multihomed Development-Laptop

Question

On my laptop I've installed an licensed a WebAS for development with NWDS. I use the laptop on different networks (different fixed IP's or no network at all). I've noticed that this somehow changes the HardwareKey and thus requires multiple licensed for the same installation.
On the other side we have an installation using DHCP and the HardwareKey does not change.
What aspects (IP, MAC, ProcessorID, RAM, Disk,...) are taken into account for generating the HardwareKey of a J2EE-WebAS?

Answer 1

Take a look at SAP Note 793649 and 174911.
There you will something like that.
"Einzig auf Windows wird ein Schlüssel genommen, der NICHT von der Hardware abhängt. Eine Neuinstalltion von Windows führt definitiv dazu, dass der Hardwareschlüssel ungültig wird."
And a list of actions who change the HardwareKey. (793649)
The following actions will change the Hardware Key:
1. Formatting the machine and reinstalling Windows.
2. When changing the computer name.
3. When changing the domain (it will not change back when returning to the previous domain).
4. On Linux - If you change the network card.
The following actions will NOT change the Hardware Key:
1. When adding a login user for the computer.
2. When changing date/time on the computer.
3. When changing the IP.
4. When adding a memory or hard drive to the computer.
If you encounter any other scenario that changes the hardware key,
