Get Service Information without WMI

presently I am writing a smal开发者_运维问答l piece of code to get the list of web services hosted on IIS in a remote system,

the working code right now is :

       string q2 = "select * from Win32_PerfFormattedData_W3SVC_WebService";
        ManagementScope scope2 = new ManagementScope(string.Format(@"\\dtp-robaro2\{1}", host, ns), options); 

        // ns here is string ns = @"root\cimv2";

        scope2.Connect();

        ManagementObjectSearcher search2 = new ManagementObjectSearcher(scope, new ObjectQuery(q2));
        foreach (ManagementObject mo in search2.Get())
        {
            Console.WriteLine(mo.ClassPath);
            Console.WriteLine(mo.GetText(TextFormat.Mof));
        }

now I was wondering if WMI is turned off on the remote system that i am querying then is there any alternative way to access the information i get with the above code?

Use tool Service Control - SC.EXE

I have converted this from VB.Net to C# so it may not be exactly correct, but this will do what you need:

public List<string> GetSites(string MachineName)
{

    List<string> siteList = new List<string>();

    DirectoryEntry iis = new DirectoryEntry(string.Format("IIS://{0}/w3svc/1/root", MachineName));    

    foreach (DirectoryEntry site in iis.Children) {

        if (site.SchemaClassName == "IIsWebServer") {
            siteList.Add(site.Properties("ServerComment").Value.ToString());

        }
    }

    return siteList;

}
