I've ran get-aduser to get all attributes but bizarrely for users it doesn't include the lastlogontimestamp. The same command from get-adcomputer does run and return that field, but get-aduser does not. any theory why that may be. lastlogondate is populated but my understanding was its not particularly accurate and lastlogontimestamp is reflective of any DC last logged into. I am unsure it this is to do with their AD setup or any other theories?
