Good morning! We recently upgraded from a Windows Server 2008 R2 server to a newer Windows Server 2012 R2 server. I installed the management server and restored the database. Everything seemed successful at first but certain groups never started communicating with the server. These computers have connections to the server and all other software seems to be working. When I tried to use the Client Deployment wizard the server sees the clients and allows me to start the deployment process but it always stays at 0% for all clients. I tried sending just the communication file and I tried sending a complete install. I tried processing the deployment as a group and one at a time to different clients. I've called tech support but I have had no luck. I was hoping someone on here might have had a similar situation and may have some suggestions on how to start the troubleshooting process.
Did the hostname/IP change? If so, see scenario 3 from this article:

You'll need tp create a new MSL.
We changed the name and IP address of the old server and then gave the new server the original hostname and IP address.
