lastLogon
lastLogon
When a user logs on, this attribute is updated on the Domain Controller that provided the authentication ONLY. Because it is only updated on one DC, that means this attribute is not replicated. While that might seem inconvenient at first, this is actually a pretty useful function. In those cases when you may want to figure out what sites a user has logged on (or not logged on), you would use this attribute. To accomplish that, you can write a quick query:
$(foreach ($DC in ((get-addomaincontroller -filter * | sort name).name) ){ $user = get-aduser chris -properties lastlogon -server $dc | select name,lastlogon ; echo “$DC – $(w32tm /ntte $user.lastlogon)” } )
When you run this command, every DC in the domain will be queried for a user account’s attribute for lastlogon. In this example, we’re looking for ‘test.new’. If you see the results come back with no value for lastlogon=, that means that user has never logged on using that particular Domain Controller. If you look at the results, the most recent logon timestamp will show the domain controller the user has last authenticated to.
So, that’s all in this blog. I will meet you soon with next stuff .Have a nice day !!!
