I have a ULS Viewer, and the Correlation ID does not even come up. I have read a previous thread that says the Web.Config file may have 2 instances of httpsessionState and that a work around would be to comment the offending one out. My web.config file does not even have this entry. Any Ideas

Hi,

Try unprovisioning CA and then reprovisioning it with the following commands:

psconfig -cmd adminvs -unprovision

psconfig -cmd adminvs -provision -port 8080 -windowsauthprovider onlyusentlm

Answer 2

Savoeurn Va's trick didn't work for me.  I was able to get this working by removing the following line:

<add name="Session" type="System.Web.SessionState.SessionStateModule" />

From my central admin web.config (C:\inetpub\wwwroot\wss\VirtualDirectories\45527\web.config).  So the final version looks like this:

 

<system.webserver>
        ...
        <modules runAllManagedModulesForAllRequests="true">

      <remove name="AnonymousIdentification" />

      <remove name="FileAuthorization" />

      <remove name="Profile" />

      <remove name="WebDAVModule" />

      <remove name="Session" />

      <add name="SPRequestModule" preCondition="integratedMode" type="Microsoft.SharePoint.ApplicationRuntime.SPRequestModule, Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />

      <add name="ScriptModule" preCondition="integratedMode" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

      <add name="SharePoint14Module" preCondition="integratedMode" />

      <add name="StateServiceModule" type="Microsoft.Office.Server.Administration.StateModule, Microsoft.Office.Server, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />

      <add name="PublishingHttpModule" type="Microsoft.SharePoint.Publishing.PublishingHttpModule, Microsoft.SharePoint.Publishing, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />

      <!-- <add name="Session" type="System.Web.SessionState.SessionStateModule" /> -->

    </modules>

Hi Lee,

 Very good information. It solved the issue and now my central administration is up and running. Thank you very much for your comment. I had been trying to solve this problem since morning. Thanks.

Please can you help me fix this error too "To use the observer role session state must be enabled for the web application"

Thank you

Hey Julady86,

So glad it helped.  Sorry I can't help with your other issue I've been out of the SharePoint world for too long now.
