IIS7 - Configuration & Scripting

Re: Microsoft.Web.Administration namespace?

I have a site that requires to check the existence of a node from with in a zone. If it does not exist then I create that node.

This is for a site that allows logged in users create a sub name like :: MyCompany.EriksNewSite.Com. This way it looks a little more personalized.

----------

The service i wrote is fairly straight forward but getting the correct data back out of the stream from the response of a dns command is a B**CH to say the least.

Service:

From web app

using System;
namespace AFCCDns
{
   public interface IAFCCDnsManager
    {
        bool CheckIfDomainZoneNodeHasRecords(string server, string zone, string node);
    }
}

----------------\

bool hasRecords = true;
            //select channel to communicate with server
            ChannelServices.RegisterChannel(new TcpClientChannel(), false);

            AFCCDns.IAFCCDnsManager remObject =
                 (AFCCDns.IAFCCDnsManager)RemotingServices.Connect
                 (typeof(AFCCDns.IAFCCDnsManager),
                 "tcp://111.11.29.111:8875/AFCCDnsQuerry");//111.11.29.111:8875

            if (remObject == null)
                Console.WriteLine("cannot locate server");
            else
            {
                hasRecords = remObject.CheckIfDomainZoneNodeHasRecords("111.11.29.111", "HomeBuildersBlog.Com", "MyCompanyName");
                Console.WriteLine(hasRecords);
            }

            return hasRecords;
        }

I am needing to querry the DNS server for records.

Basically if there is a way MS can give us a object that will have the same commands as the DNS command .exe then we are good. This is what we are in need of. BIG TIME!

There is a System.Net.Dns class that exposes some features from DNS, but not necesarilly a lot of functionality.

Could you share what operations your are looking to use from a DNS class.

Thanks

I see no one addresses the question that you had about a Microsoft.DNS.Administration.

Does anyone know when this may become available?

RobertAllan — Sun, 18 Jun 2006 15:51:04 GMT

I too would like to know this.

I am looking at IIS7 and Vista/Longhorn from the perspective of a web hoster.

I am impressed with the ability to programatically control webs and ftp sites and sql databases, but going forward, the ability to control dns, pop, smtp would make this a complete solution.

I know this isnt the forum for these topics, but perhaps some of you top IIS guns have some insight you would like to share.

Thanks

Are there any namespaces to play with microsoft dns server and smtp server just like microsoft.web.administration ?

Re: Microsoft.Web.Administration namespace?

thomad — Mon, 05 Jun 2006 04:17:48 GMT

I use the Microsoft.Web.Administration quite a bit in the End-to-End walkthrough I just published. Have a look:

Agreed. :p yeah... more reasons for upgrade too :)

Re: Microsoft.Web.Administration namespace?

TobinTitus — Wed, 31 May 2006 02:44:23 GMT

That's sort of the nature of the software industry though, right? If you didn't have new features, what what would be the point of developing new software?

Re: Microsoft.Web.Administration namespace?

Bernard — Wed, 31 May 2006 01:59:24 GMT

Expected :)

It doesn't, unfortunately, it's IIS7 only.

I do have a question, how well does this work with the previous versions of IIS ?

Re: Microsoft.Web.Administration namespace?

TobinTitus — Wed, 31 May 2006 01:32:59 GMT

I'm working on several samples using this namespace as well as writing the documentation for these APIs. If you have any questions or requests for samples, I'd love to hear what they are. I can't guarantee that I can incorporate them, but I'd love to hear feedback on these.

In general, this is one of my top favorite features of IIS -- then again, everything in IIS 7 is my top feature of IIS :)

I have the same sensation. I vote that someone guy from Microsoft to be President Of Earth.
