I am now migrating a ASP.NET web pages (.NET 2.0) to Windows 2008 R2, started IIS, SMTP, ASP.NET state server on the same machine.
Originally I have such setting on web.config, which is OK on windows server 2003.
<sessionState mode="StateServer" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" cookieless="false" timeout="20"/>
On windows 2008 R2:
On IIS, I defined that as an Application and under "Default Web Site", and defined a new applicaiton pool to it.
On "Default Web site", I define the session to use "InProc" and the application as "InProc", everything works fine, however, when I change the application to use "StateServer", the follow error happens:
Sample error detail:
