Documentation

The hierarchy spans multiple domains on the workstation side of the house and we are targeting and tracking client deployment on a per domain basis. With 11 domains and 4 queries per domain on 3 site servers I wanted to make my life a little easier so I spent some quality time with the ConfigMgr SDK and the PowerGui Script Editor to hack out a script to do it for me.

The script simply has 2 arrays that it iterates over, one for domains, and the other for the queries to create. The array for the Domains is a plain vanilla list of strings. The Array for the Queries is a bit more complex since it required more than a single piece of data per query. I used an array of hashmaps for this. There may be a more elegant way to handle this (an array of custom objects perhaps) but my days of perl have made me relatively comfortable with complex nested data structures.

All of that was simple. But issues with the Put() method on the WMI class gave me quite a bit of trouble. Apparently, the put method occasionally fails to function for no apparent reason. To resolve this I had to trap the exception and re-call the put method. That worked splendidly. After figuring out a bit more of the structure of the objects returned I was also able to spit out a nice bit of text if the creation succeeded of error out if it failed.

One major item to note, the SDK will allow you to create duplicate queries. So be prepared to delete some stuff if you play around with this script.
