Yes.  Also, keep in mind that when this happens that you can login to your My Account area of the SF website and do a manual deactivation from the web (which may be what you were referring to in your earlier post not that I think about it ).  But yes, the license binds to a MAC address of the NIC of your choice.  If that NIC is not available when SF attempts to verify licensing, then it will recognize it as an invalid license file.

First up, thanks for manual deactivation. This has saved me a couple of times. Like today.

I had my SF running nicely on my laptop. I returned to the office, launched the licence activation client, and it came up in red, because my network card wasn't plugged in. I thought that as I was looking to deactivate,  I would just progress through to the deactivation and it came up nice and green 'deactivation successful'. Great.

No. I am now working on my desktop, and I am told there are no licences available. In my account, the licences are still showing as being allocated to my laptop.

So, I guess the question is does the actual network device used have to be connected in order to acheive a proper deactivation?

thanks chaps
