I'm doing a iCal Service to allow sync between Calendar instances and runs fantastic on localhost (under VS2010 Web Server)
But now That I hosted on a Windows 2008 R2 (IIS 7.5.7600) I couldn't create not even update an event :-o
Thunderbird always said

So I rush into Fiddler and found out the problem

a 405 error

That says PUT is not allowed :(
How can I enabled this method? Application Pool? WebSite definition? IIS Settings?
