###Compiles the example
InstallExchange -ConfigurationData $PSScriptRoot\InstallExchange-Config.psd1 -Creds $Creds

###Sets up LCM on target computers to decrypt credentials, and to allow reboot during resource execution
Set-DscLocalConfigurationManager -Path .\InstallExchange -Verbose

###Pushes configuration and waits for execution
Start-DscConfiguration -Path .\InstallExchange -Verbose -Wait
