dsquery - last logon

The following gives me the last logon time of a user.  However, given the existence of products like “Real Last Logon”, my understanding is that the below query would need to be run on several domain controllers to get a accurate time.

dsquery * domainroot -filter "(&(objectCategory=Person)(objectClass=User)(sAMAccountName=%username%))" -attr sAMAccountName distinguishedName lastLogon

Can the dsquery tool target a specific domain controller to ease this burden?

Instead of lastLogon use lastLogonTimeStamp which is replicated between all DCs in a domain.

agree with Krzystof, what the tool you mentioned does hits every DC.  I haven't used it myself.

I'd use a tool like adfind http://www.joeware.net/freetools/tools/adfind/index.htm or the Quest powershsll cmdlets as they do a better job of decoding the dates


adfind -default -f "&(objectcategory=person)(objectclass=user)" samaccountname lastlogontimestamp -tdc -nodn

Thanks
