Analysis Center console won't open.
Error: 'Login Error: Web Service Error: Configuration Error.'
ACWebService URL Heartbeat or Version reports a problem in the Web Service.
AC Web Service Reports:

Please check with your IIS Administrator prior to using these steps. 

Verify your configuration with the following Microsoft KB prior to proceeding: http://support.microsoft.com/kb/828810/ with the following options in the 'Path':

/acwebservice

/Reports

/ReportServer

Then restart the IIS Service after the following adjustments:

Open web.config (located by default under inetpub\wwwroot) and make these changes:

    * In the line shown below, change "wss_minimaltrust" to "Full"

      <trust level="wss_minimaltrust" originUrl="" />
    * Remove the comment tags (<!-- ... -->) around these lines

      <add name="Session" type="System.Web.SessionState.SessionStateModule"/>
    * Enable the session state flag by adding the following lines between the <system.web></system.web> tags

<pages enableSessionState="true" enableViewState="true" enableViewStateMac="true" validateRequest="false" />

If the above information does not resolve your issue, use the steps below to modify the configuration file. 

1. Configure the SharePoint security to allow other ASP pages and programs by editing the web.config file using the command-line executable typically found on the SharePoint server in C:\Program Files\Common Files\Microsoft Shared\web server extensions\60\BIN and a name of stsadm.exe with the following additions:
   
   

   "C:\Program Files\Common Files\Microsoft Shared\web server extensions\60\BIN\stsadm" -o addpath -url http://localhost/acwebservice -type exclusion

   "C:\Program Files\Common Files\Microsoft Shared\web server extensions\60\BIN\stsadm" -o addpath -url http://localhost/Reports -type exclusion

   "C:\Program Files\Common Files\Microsoft Shared\web server extensions\60\BIN\stsadm" -o addpath -url http://localhost/ReportServer -type exclusion

2. Remove the web.config file and restart IIS to allow the AC Console and the ACWebService page to launch.  To test the change, use the following URL to return the AC version information: http ://<AC Server Web Service machine>/ ACWebService
    
3. If the change does not resolve the problem, install SharePoint to a non-default Website to avoid this restriction of IIS security by the SharePoint web.config file

In some instances, you may have to grant the ASPNET account administrative access to the local machine.  This is required by some IIS utilities or other applications.

The AC Console and the ACWebService page are ASP applications. A file required by Microsoft SharePoint is restricting ASP pages or programs from starting. The ASP Windows Component from the WWW Application is not installed. A common reason for this change to occur is installing SharePoint at the Default Website. Microsoft SharePoint installs a web.config file in the following default location: c:\Inetpub\wwwroot. This file restricts ASP pages of any sort.
