Where's CAS (lly) putting your CAS location on a map

As a bit of break from the EWS powershell series here is an interesting script that will show a Google Map of the location(s) of your CAS server's if you have them (In multiple Geographically locations) and the AD Site that the CAS Server is located in has the location property set in a format that can be Geo-coded by the Google maps API.

For this script to work you must have set the Location property of the AD site where your CAS is located in and it needs to be formatted in a Geo-code format. eg  street, city, state, zip you can test it with http://gmaps-samples.googlecode.com/svn/trunk/geocoder/singlegeocode.html eg my settings looked like


 So lets look at how the script works first we have a Get-ClientAccessServer loop

Get-ClientAccessServer | foreach-object{

The next thing the script does is jumps out to use ADSI to access the server object for the CAS

$soSvrObject = [ADSI]("LDAP://" + $_.DistinguishedName.ToString())

This script then uses ADSI to grab the Site object from the msExchServerSite property via ADSI

$siteObject = [ADSI]("LDAP://" + $soSvrObject.Properties.msExchServerSite.Value.ToString())

It then Geo-codes the address which means it gets the Lat and Long of the address location which can then be used to construct the Google Map URL and place the Map Pin

    $WebClient = new-object System.Net.WebClient
    $location = $rptObj.Location
    $baseURL = "http://maps.google.com/maps/geo?q="
    $url = $baseURL + $location + "&output=xml&sensor=false"
    $LatLonBox = ([xml]($WebClient.DownloadString($url))).kml.Response.Placemark

The rest of the script just gets the Map and displays it in a Windows Form picture box so what you get when you run the script is something like


Or a Northern Hemisphere example


I've put a download of this script here the script itself looks like
