Setting and modifying Trusted Hosts with PowerShell

TrustedHosts

## Hey folks, this is just a quick walkthrough on modifying the trusted hosts property in WSMAN using Powershell

# By default PowerShell loads a PSDrive for the WinRM service
# We modify the trusted hosts property using the Set-Item cmdlet

Set-Item WSMan:\localhost\Client\TrustedHosts -value 192.168.1.13
#This sets the value to 192.168.1.13, it also overwrites any existing values

# If you want to set a subnet you can use the PowerShell wildcard character
Set-Item WSMan:\localhost\Client\TrustedHosts -value 192.168.1.*

# both the examples above will overwrite the current value of the trustedhosts property
# to add to instead of overwriting you need to use the concatenate dynamic parameter available in the WSMAN provider
# Thanks to @alexandair for that bit of info

set-item WSMan:\localhost\Client\TrustedHosts -Value "192.168.0.*" -Concatenate

# 

# and that's all I have!  I hope this was useful to someone
