New Post: MSBuild.ExtensionPack.Web.Iis7Website fails on remote machine

Hello all.

I'm trying to configure a IIS7 Website via MSBuild and got stuck getting even a simple task running. Since I'm pretty new to MsBuild anyway my approach may be totally wrong. Any help is greatly appreciated.

Here's one of the easy Tasks that do not run:

<MSBuild.ExtensionPack.Web.Iis7Website
          TaskAction="CheckExists"
          Name="Default"
          Port="80"
          MachineName="myMachineName"
          UserName="username"
          UserPassWord="password">
            <Output TaskParameter="Exists" PropertyName="SiteExists"/>
</MSBuild.ExtensionPack.Web.Iis7Website>

Running MsBuild with this results in a COMExeption with the error code 800706ba "COM-Classfactory for Remote Component with CLSID {2B72133B-3F5
B-4602-8952-803546CE3344} could not be called from computer"

Any ideas?

Kind regards

Markus
