我在网上有一些关于检索Active Directory域的NetBIOSName(Pre-windows 2000域名)的代码。这是我的代码示例:

Me._rootDSE = New System.DirectoryServices.DirectoryEntry("GC://RootDSE", "", "")
      Dim results As System.DirectoryServices.SearchResultCollection = Nothing
      Dim ADSPath As String = "GC://CN=Partitions," + Me._rootDSE.Properties("configurationNamingContext").Value.ToString()

      Dim adse As System.DirectoryServices.DirectoryEntry = New System.DirectoryServices.DirectoryEntry(ADSPath, "", "")

      Dim searcher As System.DirectoryServices.DirectorySearcher

      searcher = New System.DirectoryServices.DirectorySearcher(adse)
      searcher.SearchScope = DirectoryServices.SearchScope.OneLevel
      searcher.Filter = "(&(objectClass=crossRef)(systemflags=3))"
      searcher.PropertiesToLoad.Add("netbiosname")
      searcher.PropertiesToLoad.Add("ncname")

      results = searcher.FindAll()

      If results.Count > 0 Then
        For Each sr As System.DirectoryServices.SearchResult In results
          Dim de As System.DirectoryServices.DirectoryEntry = sr.GetDirectoryEntry()
          'netbiosname and ncname properties returns nothing
          System.Diagnostics.Trace.WriteLine(sr.GetDirectoryEntry().Properties("netbiosname").Value.ToString())
          System.Diagnostics.Trace.WriteLine(sr.GetDirectoryEntry().Properties("ncname").Value.ToString())
        Next
      End If

当我使用“(&(objectClass = crossRef)(systemFlags = 3))”过滤器时,我没有得到任何结果,但是当我删除systemFlags过滤器时,我得到了一些结果。

但是,在我得到的搜索结果中,我仍然无法访问ncName和NetBIOSName属性的值。我可以正确地获得搜索结果的其他属性,如distinguishedName和CN。

关于我可能做错了什么,或者在哪里看得更远的任何想法?

我找到了一个解决方案,我不知道这是不是正确的,但它确实有效。我从

更改了ADSPath的值
Dim ADSPath As String = "GC://CN=Partitions," + Me._rootDSE.Properties("co..

Dim ADSPath As String = "LDAP://<server>/CN=Partitions," + Me._rootDSE.Properties("co..

我提供了LDAP服务器地址,一切都解决了。现在,如果只能以编程方式获取LDAP服务器的IP地址或FQDN,我将不必使用配置文件来存储LDAP服务器的值。
