Hello, I have a Certification Authority on a Windows 2008 Enterprise, SCCM SP2 and a Verisign certificate. I try to make a provisioning a computer without SCCM client. I connect to the network and start sending messages "Hello", but in the amtpmgr.log shows me the following: Start processing incoming hello message from 10.100.1.3:16994.
