msbuild - unauthorizedAccessException: Retrieving the COM class factory for remote component with CLSID {2B72133B-3F5B-4602-8952-803546CE3344

Question

I am using MSBuld task to change the virtual directory of an IIS Site hosted on windows 2012 server. I am using following code:

<MSBuild.ExtensionPack.Web.Iis7Website TaskAction="Stop"
                                               Name="TestSite"
                                               MachineName="$(MachineName)"/>
        <MSBuild.ExtensionPack.Web.Iis7Website TaskAction="ModifyPath"
                                               Name="TestSite"
                                               Path="$(PublishDir)"
                                               MachineName="$(MachineName)"/>
        <MSBuild.ExtensionPack.Web.Iis7Website TaskAction="Start"
                                                                     Name="TestSite"
                                               MachineName="$(MachineName)"/>

I am performing two task:

1. Copy files from my machine to remote machine, which is working fine. Meaning I have read and write access on remote machine.
2. In the step two, I am trying to change the virtual directory using ms build task, which is failing.

I am getting following error when I try to change the virtual directory of a IIS site either on same machine or on different machine.

UnauthorizedAccessException: Retrieving the COM class factory for remote component with CLSID {2B72133B-3F5B-4602-8952-803546CE3344} from machine XXXX failed due to the following error: 80070005

I am using same code on windows 2008 server to change virtual directory path of another website hosted on a different machine & it is working fine.

I looked around for similar issue & most of the people talking about suing user-name and password of a person having admin right other machine or make some changes in registry. I do not want to use these two approaches.

Is there any other work around?

Answer 1

As it turned out, I was running the task using Team City (continuous integration server) which in turn used ms-build task to change the virtual directory. Team city was running under a service account. I had to add that service account under Administrators group on the remote machine.
