    I've got some Problems when I try to filter all Users that have logged On since a given Time.

    I've set the PageSize to 8 and the sizeLimit to 500. After 1500 Users, I've got to wait some time and then I get 10-15 Users more, bevore the COM-Exception 'More Data is available' is thrown. Is the timeout been hit? And why does it take so long to find the Users?

    Dim de As New DirectoryServices.DirectoryEntry("LDAP://DC=xxx,DC=xxx,DC=xxx")
    Dim dom As DirectoryServices.ActiveDirectory.Domain        
    Dim myResultCol As System.DirectoryServices.SearchResultCollection
    Dim mySearcher As System.DirectoryServices.DirectorySearcher = New DirectoryServices.DirectorySearcher(de)
    mySearcher.Filter = "(&(lastLogon<=" & Date.Now.ToFileTime & ")(&(c=DE)lastLogon>=127921762767754646))"
    mySearcher.PageSize = 8
    mySearcher.SizeLimit = 500
    myResultCol = mySearcher.FindAll
    For Each SResult As System.DirectoryServices.SearchResult In myResultCol


    Thanks and greez

    Yech.  A page size of 8 is going to incurr a TON of network trips.  The SizeLimit is ignored when using paging as well.  It is an either/or proposition.  Try using a page size of somewhere between 500 to 1000 and your query stands a chance.

    I've changed the Filter to

    >mySearcher.Filter = "(&(objectCategory=person)(lastLogon>=" & startTime & "))"

    and changed PageSize and SizeLimit. Now it works and I get all User that have Logged on since a given time :)
