I had already used the command: CSVDE -f aduser.csv to export all LADP Attribute parameter. However, I want to find a attribute that mean which PC (Hostname) a user logon currently. Please tell me which one, Thank you.

there is no such attribute. You have to wirite a script that writes desired information to the user properties.

Hi, As Roman said, there is no such an attribute. Active Directory does not keep track of which users logon from which workstations. You can find mappings between User object attributes and LDAP properties from the following article: LDAP User Object http://msdn.microsoft.com/en-us/library/aa746388(v=vs.85)) You could use logon scripts to log the user and the computer name to a shared log file like this(%computername% variable indicates which computer a user logs on): echo logon %username%,%computername%,%date%,%time% Regards, Cicely
