c# - 如何确定我使用的机器是否是域 Controller

Question

使用 C#，如何确定运行我的代码的机器是否是域 Controller 。

我不想“出去”并收集有关域中任何其他域 Controller 的信息...我只对运行我的代码的机器是否是域 Controller 感兴趣。此外，我不需要知道它是否是主域 Controller ...只要它是域 Controller 即可。

这是我尝试过的

试验 1

    private bool IsDomainController()
    {
        Domain domain = Domain.GetCurrentDomain();
        string domainName = domain.ToString();
        bool bIsDC = false;
        DirectoryContext ctx = new DirectoryContext(DirectoryContextType.Domain, domainName);

        try
        {
            using (DomainController dc = DomainController.FindOne(ctx, LocatorOptions.ForceRediscovery))
            {
                bIsDC = true;
            }
        }
        catch (Exception)
        {
            bIsDC = false;              
        }

        return bIsDC;
    }

和

试验 2

    public bool IsThisMachineIsADomainController()
    {
        Domain domain = Domain.GetCurrentDomain();

        string thisMachine = String.Format("{0}.{1}", Environment.MachineName, domain.ToString());
        thisMachine = thisMachine.ToLower();

        //Enumerate Domain Controllers
        List<string> allDcs = new List<string>();

        string name = "";
        foreach (DomainController dc in domain.DomainControllers)
        {
            name = dc.Name.ToLower();
            allDcs.Add(name);
        }
        return allDcs.Contains(thisMachine);
    }

这些是否合适，为什么或为什么不合适？

Answer 1

经过大量研究...有两种方法:

适用于 Windows 2008 服务器:

    public bool isActiveDirectoryDomainServicesInstalled()
    {
        bool bRetval = false;
        try
        {
            uint uID = 110;
            string search = string.Format("SELECT * FROM Win32_ServerFeature WHERE ID = {0}", uID);
            ManagementObjectSearcher oSearcher = new ManagementObjectSearcher("root\\CIMV2", search);

            foreach (var oReturn in oSearcher.Get())
            {
                if ((uint)(oReturn["ID"]) == uID)
                {
                    bRetval = true;
                    break;
                }
            }
        }
        catch (Exception)
        {
            bRetval = false;
        }

        return bRetval;
    }

.和.

适用于 Windows 2008 和 Windows 2012 服务器

public bool IsThisMachineIsADomainController()
{
    Domain domain = Domain.GetCurrentDomain();

    string thisMachine = String.Format("{0}.{1}", Environment.MachineName, domain.ToString());
    thisMachine = thisMachine.ToLower();

    //Enumerate Domain Controllers
    List<string> allDcs = new List<string>();

    string name = "";
    foreach (DomainController dc in domain.DomainControllers)
    {
        name = dc.Name.ToLower();
        allDcs.Add(name);
    }
    return allDcs.Contains(thisMachine);
}
