Hi @Gblenn ,
thank you for your information, I just find out they use a split tunelling VPN .... so some of the software on the work PC pass through the VPN.
So that is why Chrome see the Chrome-cast on my Lan.
Your right they ca do whatever they want on that PC.
The document I saw was not for me to view, it was an error, but I had time to see a quick 2 sec results.
Again, thank you for your information.
I have my response a long time ago : can we stop this thread now?
Thank you all, Richard.
