title: Access denied when trying to read information about SharePoint groups
body: <p>I am trying to get the membership of a group in WSS 3.0. I am doing this in an elevated permissions block. Here is the code:</p>
  
  <pre>
  SPSecurity.RunWithElevatedPrivileges(delegate()
  {
     using (SPSite site = new SPSite(SPContext.Current.Site.ID))
     {
        using (SPWeb rootWeb = site.RootWeb)
        {
           SPGroup gAdmins = rootWeb.SiteGroups["Admins"];
        }
     }
  });
  </pre>
  
  <p>I get taken to the "access denied" SharePoint screen when I run this code. 
  The group exists. The identity of the application pool for the web application is in the dbo role in the content database.
  The code works on my development server, but not on another server, which leads me to believe there is something wrong with the permissions or configuration on this server, maybe something in dcomcnfg?</p>
  
  <p>Here are some lines from the SharePoint log that seem to be related:</p>
  
  <pre>PermissionMask check failed. asking for 0x08000000, have 0x00000000    
  Unknown SPRequest error occurred. More information: 0x80070005   
  Access Denied for /Pages/UserAdmin.aspx. StackTrace: Microsoft.SharePoint.Utilities.SPUtility:Void HandleAccessDenied(System.Exception), Microsoft.SharePoint.SPGlobal:Void HandleUnauthorizedAccessException(System.UnauthorizedAccessException), ....</pre>
  
  <p>[UserAdmin.aspx hosts my custom web part containing the code]</p>
