So a quick install, reveled some issues with the Deplay Agent task on some servers.. failing with this error:
Failed to deploy the Agent. Could not connect to net.tcp://ex-cas.contoso.com:8816/PushInstaller. The connection attempt lasted for a time span of 00:00:21.0157595. TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 192.168.5.20:8816.
Quick workaround, just configure the Firewall State for the specific failed servers for the domain profile to off :) or, configure the inbound port 8816 from the FPSMC consle server to that server..
Just a heads up for anyone who sees this.
Happy holidays !
