#Requires -Version 3.0
# Configure a Windows host for remote management with Ansible
# -----------------------------------------------------------
#
# This script checks the current WinRM (PS Remoting) configuration and makes
# the necessary changes to allow Ansible to connect, authenticate and
# execute PowerShell commands.
#
# All events are logged to the Windows EventLog, useful for unattended runs.
#
# Use option -Verbose in order to see the verbose output messages.
#
# Use option -CertValidityDays to specify how long this certificate is valid
# starting from today. So you would specify -CertValidityDays 3650 to get
# a 10-year valid certificate.
#
# Use option -ForceNewSSLCert if the system has been SysPreped and a new
# SSL Certificate must be forced on the WinRM Listener when re-running this
# script. This is necessary when a new SID and CN name is created.
#
# Use option -EnableCredSSP to enable CredSSP as an authentication option.
#
# Use option -DisableBasicAuth to disable basic authentication.
#
# Use option -SkipNetworkProfileCheck to skip the network profile check.
# Without specifying this the script will only run if the device's interfaces
# are in DOMAIN or PRIVATE zones. Provide this switch if you want to enable
# WinRM on a device with an interface in PUBLIC zone.
#
# Use option -SubjectName to specify the CN name of the certificate. This
# defaults to the system's hostname and generally should not be specified.
