Read my post about (Shared Services Provider stuck on "Provisioning in Progress) for a background on why I ran into this issue.
First, make sure that you have a Shared Services Provider running. You can check this by going to your Sharepoint Central Administration website and on the left hand navbar you should see at least 1 item listed under "Shared Services Administration".
Once you verify that you have an SSP setup, go to Application Management and under the heading "Office SharePoint Server Shared Services" click the link for "Configure session state"
You should be able to check the "Enable Session State" checkbox like the screenshot below
Be sure to save your settings.
I also read that in your sites web.config file you can uncomment the following line (but apparently this isn't the MS Best Practice)
<!-- <add name="Session" type="System.Web.SessionState.SessionStateModule"/> -->
and also set the "enableSessionState" attribute to "true" in the element below (also in the web.config).
<pages enableSessionState="false" enableViewState="true" enableViewStateMac="true" validateRequest="false" pageParserFilterType="Microsoft.SharePoint.ApplicationRuntime.SPPageParserFilter, Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" asyncTimeout="7">
Unfortunately, neither the setting up of the SSP or web.config settings rid me of the error message "The form cannot be displayed because session state is not available" I kept getting when trying to create a simple approval workflow. Since I was able to bypass the issue, I will leave this in the back of my mind, but if anyone has an suggestions I am all ears.
