Error while publishing Lightswitch application remotely from Windows 7 PC to Windows 2003 Server having IIS 6.0

Question

I am trying to publish a LightSwitch 2012 application as Web Application from Windows 7 PC to Windows 2003 IIS server, .Net Framework 4.0
The publish Summary as follows
Application Name - User Test
Application Version - 1.0.6.0
Application Type : Browser
Application Server : IIS Server
Authentication : Windows Authentication
Database : Do not publish
Error details while publishing with the option "IIS server has lightswitch deployment prerequisites installed". 
============================================================================
102 Web deployment task failed. (15/04/2014 16:24:51) An error occurred when the request was processed on the remote computer.)
(15/04/2014 16:24:51) An error occurred when the request was processed on the remote computer. The entry type 'unknown' was not expected at this time. The serialization stream may be corrupted.
When published without the option "IIS server has lightswitch deployment prerequisites installed".
the applications publishes successfully, But when the application is accessed from Browser it says authentication error.
I have searched a number of blogs with the same issue, but none have answered. 
Any help will be highly appreciated.

Answer 1

I am once again facing the same issue when trying to publish remotely.  But I have done nothing to the server after successful publishing as suggested below,
Not sure why the issue persists again (Could this be  a firewall issue?) . Your help will be much appreciated.

Finally, I Could able to resolve the issue.  I have identified the below information for a successfull deployment
1. Light switch 2012 application can be published only with Web Deploy 1.1 (which will create Web Deployment Agent Service) in Windows Services list.  I had an issue with multiple Web Deploy versions (Web Deploy 2.0, 3.0) which caused to fail the publishing
from Light Switch Development environment. Un-installed all the versions and installed only Web Deploy 1.1 and then published successfully
2. You should use Remote Publish from Light Switch 2012 Development PC as there is no option in IIS 6.0 to import the Package in IIS 6.0 with the packages files similar to the option available in IIS 7.0 and later.
3. You should be able to publish from Light Switch 2012 environment with the option "IIS server has lightswitch deployment prerequisites installed" checked.  The application will publish with the option unchecked but it will not work.
