Hi, We are runnig 3CX 9 on a Hyper-V virtual machine and everything is fine. However, we did a backup and restore test of the 3CX virtual machine towards another Hyper-V server and we encountered the following problem: It seems like 3CX doesn't recognize the network adapter on the new virtual server. A lot of features are not working, trunks are not registering, phones are not connecting. I think that there's an "ID" somewhere for the network adapter that 3CX can't find. I will try to reproduce the problem later this week and give more information. I know I could restore a 3CX backup on a new installation, but I want to be able to restore a virtual machine with 3CX on it without any problems. Thank you.
