Today I needed to find the changedate for some of the attributes of a specified used. The obvious answer here was PowerShell (duh!) and here is the small script I came up with as a quick and dirty (somewhat modified to be more generic than my original implementation). The scripts pulls up the default context (domain) and a random domain controller and polls that machine for metadata. The results are returned for further processing. Download the script and rename it to .ps1 and try it out!
