Active Directory Last Logon Tools

Active Directory Last Logon Tools

I was looking for some tools that will enable you to see when last a person have used there user ID to login toe your domain. This is helpful to find out account of people that might have left the company.

In my search I have come past a couple of programs and script that can do this.
The first program I fount is called True Last Login. It works very well and you can download a freeware version with some limitations.
The second program is called Inactive Users Tracker. It will also search your domain en display a list of last login user ID.

The other way to do this is to use a VBscript. There is a couple of them out there, some work better then others. The one that I found that works the best so far is the one I found Here.
Below is the script in case the link above does not work.
Just copy and path the text below into a text document and rename it to lastlogin.vbs
Then run the following command in command prompt. This will redirect the output to a text file.
cscript //nologo lastlogint.vbs > output.txt

‘ LastLogon.vbs
‘ VBScript program to determine when each user in the domain last logged
‘ on.

‘ Version 1.4 – February 19, 2003 – Standardize Hungarian notation.
‘ Version 1.5 – March 11, 2003 – Remove SearchScope property.
‘ Version 1.6 – May 9, 2003 – Account for error in IADsLargeInteger
‘ property methods HighPart and LowPart.

‘ Because the lastLogon attribute is not replicated, every Domain
‘ Controller in the domain must be queried to find the latest lastLogon
‘ date for each user. The lastest date found is kept in a dictionary
‘ object. The program first uses ADO to search the domain for all Domain
‘ Controllers. The AdsPath of each Domain Controller is saved in an
‘ array. Then, for each Domain Controller, ADO is used to search the
‘ copy of Active Directory on that Domain Controller for all user
‘ objects and return the lastLogon attribute. The lastLogon attribute is
‘ a 64-bit number representing the number of 100 nanosecond intervals
‘ since 12:00 am January 1, 1601. This value is converted to a date. The
‘ last logon date is in UTC (Coordinated Univeral Time). It must be
‘ adjusted by the Time Zone bias in the machine registry to convert to
‘ local time.

If you know of any other or beter way to do this please let me know.
