Get members from a Domain global group over LDAP

[antem]

I receive only members from domain global goup in wich my NT-Account is too.
If domain global group belongs to a foreigner domain i get no members.
Perhaps I will not be able cause I got not enaugh rights. So I start to search only for goupnames and a users in foreigner Domains and I get all Information.
Next step I start to search the member with the Windowsexplorer and I recive also all members of the foreigner domain global group.

I belong to the domain de.firma.com
The foreigner Domain us.firma.com

strPath = "GC://dc=firma,dc=com"
 
        strGroupName = groupName
 
        Try
            objADAM = New DirectoryEntry(strPath)
            objADAM.RefreshCache()
        Catch e As Exception
            MessageBox.Show("LDAP-Name unbekannt!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
            Return
        End Try
 
        Try
            objSearchADAM = New DirectorySearcher(objADAM)
            ' Mögliche Werte für ObjectClass: Group; User, Printer, Computer etc.
            objSearchADAM.Filter = "(&(objectClass=*) (cn=" & strGroupName & "))"
            objSearchADAM.SearchScope = SearchScope.Subtree
            objSearchResults = objSearchADAM.FindAll()
        Catch e As Exception
            MessageBox.Show(e.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
            Return
        End Try
 
        ' List groups and members.
        Try
            If objSearchResults.Count > 0 Then
                Dim objResult As SearchResult
 
                For Each objResult In objSearchResults
                    objGroupEntry = objResult.GetDirectoryEntry()
 
                    Dim members As Object = objGroupEntry.Invoke("members", Nothing)
                    For Each member As Object In CType(members, IEnumerable)
                        ' Read Surename,Givenname and Department 
                        Dim strNTUsernameDetails As String = ActiveDirectoryUser.Exists(strNTUsername)
                        If strNTUsernameDetails Is String.Empty Then
                            groupEntries.Add(strNTUsername)
                        Else
                            groupEntries.Add(strNTUsernameDetails)
                            strNTUsernameDetails = String.Empty
                        End If
                    Next member
 
                Next objResult

Have you tried a sperate query for each domain?

Have you tried a sperate query for each domain?

Oooooh noooo. That's it. Thanks a lot. However, why I get no members if I take the Domain firma.com? I try it with the Domain us.firma.com an I get all member. Im working in a Big Big Domain. About 800 Domains. Maybe the reason is the big value of Domains.
