Visual Studio 2005 - Unable to make the session state request to the session state server.

 Hi,
 I have recently been given a PC with Vista on it, and installed Visual Studio 2005 pro. I then moved a ASP.net web project from an XP machine to the Vista one.
 When I run the project from inside Visual Studio (debug mode) everything works fine on the front end of the website, but if I try and log in I get the following error:
 
 Unable to make the session state request to the session
state server. Please ensure that the ASP.NET State service is started
and that the client and server ports are the same.  If the server is on
a remote machine, please ensure that it accepts remote requests by
checking the value of
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servicesspnet_state\Parameters\AllowRemoteConnection.
 If the server is on the local machine, and if the before mentioned
registry value does not exist or is set to 0, then the state server
connection string must use either 'localhost' or '127.0.0.1' as the
server name. 

            

             Description: An
unhandled exception occurred during the execution of the current web
request. Please review the stack trace for more information about the
error and where it originated in the code.

The registry key given in the error does not exist in my registrey, and the ip address for the state server is set to 127.0.0.1 in my web.config file. I've seen posts on other forums about this, but none of the solutions given work for me.
Any help would be much appriciated,
Robin 

The StateService is not set to start by default because the default mode for session is in-process.  If you are configured to use the StateServer service, then you need to change that service to start automatically.
This is done from the Services section of your systems Control Panel

 Thanks for your help.
Unfortunately I cannot find the State Server listed anywhere in the services control panel. Is it called something else (I have looked for ASP state server as well). Is this something that doesn't comes as standard with Vista Business and I need to get from somewhere and install?
 I'm sorry to sound so uninformed but I usually develop on a LAMP stack, all this Windows stuff is new to me.
 

Hi Robin,
The name of ASP.NET state service is €œASP.NET State Service€. If you cannot find it in Windows Service, pleaes make sure you have installed ASP.NET properly, you may try to reinstall ASP.NET 2.0 via exectuing the following commands:
    C:\WINDOWS\Microsoft.NET\Framework2.0.50727spnet_regiis €“u
    C:\WINDOWS\Microsoft.NET\Framework2.0.50727spnet_regiis €“i
In additiion, there is a known issue of installing ASP.NET state service with the 32-bit ASP.NET 2.0 on 64-bit computer. You can see detailed information on the following link. Hope it is helpful to you.
The ASP.NET state service (Aspnet_state.exe) is not installed when you install the 32-bit version of ASP.NET 2.0 on a 64-bit computer

Hello. I was browsing around trying to find a solution to my problem and came across this post, which describes a situation quite similar to the one I'm having. I also migrated from XP to Vista, with the difference that I'm using ASP.NET 3.5 and VS 2008. I have already set ASP.NET state services to automatic (the original poster's problem seems to be he couldn't find it), and the session state parameter is set to 127.0.0.1:42424 in the web.config file (the port 42424 matches the port set on windows registry). However, the problem remains the same. Any pointers?

Nevermind, I had set the service to automatic but forgot to start it...
