AMT DTK Development in a web page

[cjdouglas]

Hi,

I hope it's not too silly a question. I have for some time been using the AMT DTK libraries within windows forms (created in Visual Basic .Net 2005/2008) to do simple things like return the power state of a PC. I would very much like to move to a web based application again using VB.Net to create an ASPX web page. All seems well in my development environment, but when I move to a real IIS6 web server I get errors! It appears that when the IAMT dll's are registered it all goes horribly wrong, am I missing something? Has anyone else managed to do this?

Thanks

Craig

Hi there. I have never used the DTK libraries as part of an ASP.net project, so, I don't have a clear answer. First, none of the DTK dll's must be registered, if you try it will fail. They don't include any COM objects, they are just .NET dll's. If you can manage to run full .NET code within ASP.net, you should be able to use IntelAmtStack.dll, but since I don't know ASP.net at all, I am not sure how to help. Can you send over the errors you are gettins?

Hi,

Thanks for the reply, below is the debug text as observed on the server (which is 2003R2 x64 by-the-way). Any help would be terrific.

Hi,

We are working on this. Will get back to you soon.

Thanks,

Hi,

That would be terrific. :-)

Any and all help gratefully received.

Thanks

Oh dear, this is not good. I have no idea how to get started with this one since I am not familiar with ASP.net at all. First, performing a LoadModule on IntelAmtControl.dll should work. One thing you have to make sure to do is take IntelAmtStack.dll and IntelAmtControl.dll from the same DTK distribution. If you take files from two different distributions, it may cause this to happen. Also note that IntelAmtControls.dll does make use of IntelAmtStack.dll, so make sure both files are in the same directory. You may also need IMRSDK.dll if your going to do SOL/IDER and you may need OpenSSL folder if you perform certificate operations, etc. The only immidiate dependency should be IntelAmtStack.dll.

Otherwise, I am stumpted.

Hi,

I'm actually not doing anything complicated, don't even anticipate getting into the realms of SOL/IDER. What happen is, I create a Web Site in Visual Studio (ASP.Net - Visual Basic), it can be just a simple as text on the page (Hello World sort of thing). When I up load to the web server everything is ok (as you would expect). However, as soon as I add references to the IntelAmtControls.dll and IntelAMTStack.dll it runs fine on my machine (running the ASP.Net Development Server) but when I upload to the IIS server it errors as prviously described. I don't even have to add code which calls the dlls, just their presence seems enough to upset it.

Does this help clarify anything?

Regards

Craig

[Sreelekshm_S_Intel]

Hi,

As Ylian suggested, did you confirm that you are taking both the dlls from the same distribution?

Thanks,

Sree

[cjdouglas]

Hi,

They are bothe coming from the same DTK version, is that what you mean. I initially started with an older one (can't rememver the version number now), but when it didn't work I updated to the latest from the Intel site (0.35?). Still no joy . But in both instances the dll's in use came from the same source.

Hi,

We have a later version of DTK (v0.52) at http://software.intel.com/en-us/articles/download-the-latest-version-of-manageability-developer-tool-kit. Could you please try that?

Thanks,

Sree

[cjdouglas]

Hi,

I have just checked this morning ant it is indeed the 0.52 version I'm using, sorry my mistake. The installation package I used was Intel_AMT_Developer_Tool_Kit_v0.52x.msi.

Regards

Craig

[Ylian_S_Intel]

I don't think the DTK version would help much in this case. I am stumped on this one since I never used ASP.net and don't have the setup of time to dive into this one. Of course, the full source is available and you could grab all the Intel AMT Stack classes you need and add them to a DLL you know works correctly. Otherwise, we need an ASP.net genious to fix this.
