only a medium to author and enact the configuration onto nodes. The Local Configuration Manager (LCM) agent on the target
nodes, ensures that systems are configured according to the configuration declaration. In Pull mode, the server is defined as a Pull
Server. The Pull Server has web services running which initiates a handshake between the server and the client systems. The server
contains the MOF at a standard location, and whenever there is a change in the checksum associated with the MOF file, the client
machine(s) pulls the configuration from the server and enforces it on the client systems. In Pull mode the LCM of the client
system(s) is set to Pull mode. These settings of the LCM are called meta – configuration.
Desired State Configuration Logs can be viewed using Windows Event Viewer. Configuration drifts on Dell client systems are
recorded in this event log at Applications and Service Logs -> DellClientBIOS PowerShell.
