Hi chad-bisd
Thank you for your replies.
It was me, I have been overlooking… I found it after check each laptop (30+) - it was active in 2 of them. It is a remote site and though they are instructed to connect to the local wifi after imaging, it looks like it has not happened. I should have checked instead of assuming…
Now the laptops are roving and connecting in via Cisco VPN, (mostly via wireless) thus it does not register the MAC over the VPN…
Ohh well, have to gather the MACs by some other method…
Thanks again for your help.
Steve
