How often is lastLogonTimeStamp updated?
If the value is older than 14 days the lastLogonTimeStamp attribute is updated with the current time. The 14 day check is to avoid overloading the AD replication and is controlled by the ms-DS-Logon-Time-Sync-Interval attribute in the domain naming context.
How accurate is lastLogonTimeStamp?
Lastlogon is precise but shows when the user logged in to that specific DC and is not replicated to others. Basically Lastlogontimestamp is great for your purpose of finding stale objects in AD, but it is not very precise.
Why is lastLogon and lastLogonTimeStamp different?
The main difference between lastlogon and lastLogonTimeStamp is that lastlogon is updated on the Domain Controller after the user interactive logon while lastLogonTimeStamp is replicated to all Domain Controller in AD Forest, the default value is 14 days. The Lastlogon attribute is not replicated.
What is lastLogonTimeStamp in Active Directory?
This is the time that the user last logged into the domain. This value is stored as a large integer that represents the number of 100-nanosecond intervals since January 1, 1601 (UTC). Whenever a user logs on, the value of this attribute is read from the DC.
Is lastLogon replicated?
The lastLogon attribute is not replicated. So in the past to determine the most recent logon of a user or computer account the lastLogon attribute had to be queried on all domain controllers (at least in concept) and then the most recent date for lastLogon had to be determined from all the results returned.
What is pwdLastSet?
pwdLastSet - MSDN. Purpose: This attribute stores the value of the date and time when the user's password was last changed in Windows NT. If the value is zero, then the user has never logged on.
How is Lastlogontimestamp calculated?
Whenever a user logs on, the value of this attribute is read from the DC. If the value is older [ current_time - msDS-LogonTimeSyncInterval ], the value is updated. The initial update after the raise of the domain functional level is calculated as 14 days minus random percentage of 5 days.
What is Lastlogondate in Active Directory?

These examples are intended to demonstrate that lastLogontimeStamp is being updated within the window of 9-14 days and replicated to all DC’s in the domain. They are not an example of how to manage stale accounts.
Why randomize lastLogontimeStamp?
This randomization is done to prevent an update of the lastLogontimeStamp attribute from many accounts at the same time causing a high replication load on the DC's . Remember the purpose of the lastLogontimeStamp attribute is locate inactive accounts not provide real-time logon information.
Why is lastLogontimeStamp important?
It is important to note that the intended purpose of the lastLogontimeStamp attribute to help identify inactive computer and user accounts.

What is the ms-DS-Logon-Time-Sync-Interval attribute?
It is an attribute of the domain NC and controls the granularity (in days) with which the lastLogontimeStamp attribute is updated. The default value is 14 and is set in code. Meaning that if you look at this attribute in ADSIEDIT.MSC and you see it as "Not Set" don't be alarmed. This just means the system is using the default value of 14.
Can you change the last logon time stamp?
It is possible to change the frequency of updates to the lastLogon Time stamp or turn it off completely if desired. If you need a different time interval you will need to adjust the value of the msDS-LogonTimeSyncInterval attribute to a value between 5-100,000. Yes that’s right: the max value is 100,000 days… Or if you prefer ~280 years... And the max value was set in code not in the schema. (I guess the dev was counting on medical science to solve that pesky aging problem.)
Does acctinfo.dll show lastlogontimestamp?
For example acctinfo.dll that is included with the Account Lockout tools will display the lastLogon attribute data not the lastLogontimeStamp data. In some cases the date the tool reports may be months or years out of date or display nothing at all.

Is the Last Logon attribute replicated?
This attribute is not replicated and is maintained separately on each domain controller in the domain. To get an accurate value for the user's last logon in the domain, the Last-Logon attribute for the user must be retrieved from every domain controller in the domain. The largest value that is retrieved is the true last logon time for that user.
Title
What is the difference between the 'lastlogon' and 'lastlogontimestamp' attributes?
Description
What is the difference between the 'lastlogon' and 'lastlogontimestamp' attributes?
Resolution
The "lastlogontimestamp" attribute is replicated in the domain every two weeks. The 'lastlogon' attribute is not replicated. However Reporter will check the 'lastlogon' data on every domain controller, compare the values and display the latest logon value.
