KB9691: How to enable Windows Authentication for MicroStrategy Office in IIS.

Like Strategy Desktop and Strategy Web, users can log into a project from Strategy Office using Windows Authentication mode when the Strategy Office Web Services are hosted on a Microsoft IIS Web Server.
To implement this feature, perform the following steps:

• Go to the Strategy Web Services machine and locate the ProjectSource.xml file under C:\Program files\Strategy\Web Services. Change the 'AuthMode' node to 'MWSNTCredential', as shown below:
   
  <ProjectSource>
  <ProjectSourceName>Strategy Tutorial</ProjectSourceName>
  <ServerName>localhost</ServerName>
  <AuthMode>MWSNTCredential</AuthMode>
  </ProjectSource>
  
• Go to Internet Information Service management console and click on the Strategy Web Services virtual directory then go to Authentication:
  

• Make sure that ASP.NET Impersonation and Windows Authentication are enabled and Anonymous disabled as seen below:
  

• Restart the Web Server.

As the screen shot below indicates, My First Project is using Standard Authentication:
