Let me know if you need any additional assistance. Best of luck!
I need to know if you are speaking strictly of vPro configuration or if you just meant "How to use vPro with Service Manager." Service Manager does not perform vPro configuration but it does access vPro features on pre-configured systems. Configuration Manager is the Microsoft app that performs vPro configuration.
To access the KVM vPro feature you do not need to deploy any software to the client. vPro features on the client need to be configured at the time of access though.
The command line you gave for KVM contains credentials that were likely part of reference scripts supplied by Intel and were intended to be changed by users. The given credentials should be changed to match user that was granted access to vPro KVM features during vPro configuration.
