Hmmm...I must not be understanding how to do that. After the license was deactivated (on the machine with the disappearing NIC), I couldn't do anything with the license. I.e. The NIC came back online, but the license activation reported that the machine wasn't licensed and then went out to the web site and reported back that there were no licenses available. Here is what I saw:
1. Licensed on machine using wired NIC.
2. Disconnected cat 5 cable, turned on wireless adapter
3. Went to use SF security, license was invalid (wired NIC had disappeared from machine)
4. Opened SF license manager to deactivate so I could activate using wireless NIC
5. License manager reported that SF wasn't licensed on the machine. Clicking next indicated that no licenses available.
6. Turned off wireless, plugged cat 5 back in, NIC shows up
7. Opened SF license manager again, still reporting that I have no license
8. Clicking next again reported no licenses available.
I must be missing something here.
So, I'm pretty much stuck at this point. I still can't deactivate via the web and I can't activate using the license manager.
