ASP.NET increasing session timeout

I have a Wizard control that I am emulating a CreateUserWizard so I can customize the steps/creation of the account.  I've found a short coming in this because I place the user info (user name, password details) in step 1 of 6 of my wizard so by the time the user is to step 6 to create their account I can't access the text ouf of the password box.  

What I've done is placed it in a session variable like so:

Session.Add("ptxt", Password.Text)

then when I am ready to make the account I read it back in:

         Dim _password$ = Session("ptxt").ToString()

My wizard is somewhat lengthy so the session is timing out from step to step 6.  I've added this in my web.config:

<sessionState timeout="540"/>

doesn't seem to do anything.  From what I understand that should be 9 hours.

so I also editted it in IIS7 which had set it to a default of 20 minutes to 10 hours.  That doesn't seem to work either.

Is there somewhere else I should be altering this?  Another way to store the password would be ok and preferrable actually.  Any thoughts or idea would be much appreciatiated and thanks as always experts!!

There are the machine.config and web.config in the ASP.Net folder, but the root web.config should overwrite these. It wouldn't hurt to try.

The other thing to consider is if you are behind a load balancer because a user may be redirected to a different server than they started on and this can be adjusted by increasing the timeout as well.

The other option to look in to is to shorten the wizard steps of create an AJAX timer that simply posts to the server to keep the session alive.
post the web config... make sure it is not commented...

http://msdn.microsoft.com/en-us/library/system.web.sessionstate.httpsessionstate.timeout.aspx

a sample web.config below
<configuration>
  <system.web>
    <sessionState 
      mode="InProc"
      cookieless="true"
      timeout="30" />
  </system.web>
</configuration>

i dont have inproc and cookieless could that make a difference?
i think that might have fixed it, i'll let you guys know
well now that i set in proc I am getting this stuff in my url

http://www.site.com/(S(tk5fafyjubpv41ff25mbvc45))/Default.aspx?aID=85202...

is that something session related it is showing?
that one comes from cookiless=true :) remove that line
Object reference not set to an instance of an object.

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.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

still not working, let the page time out for about ~20 minutes and i still got the error that the session variable is gone
Ali, thanks for the deleted response :).  But I have a question, I'm getting this error trying to set the window status text.

Error      22      'KeepSessionAlive.WindowStatusText' is not accessible in this context because it is 'Private'.      C:\work\GiveAwayUSA\KeepSessionAlive.aspx      1      1      C:\work\GiveAwayUSA\
oh nevermind, just didnt declare properly... too early in the morning i'll let you know if that worked.
Well,

Ultimately Ali's answer that was removed was the answer to my problem.  The KeepSessionAlive.aspx worked perfectly and resolved this issue.  He deserves credit, if maybe he can repost the link to his reference I'd love to assign him the points!

Thanks again for all your help experts.
