SharePoint 2010 Technology Stack

A diagram helps to demonstrate the Technology Stack for SharePoint 2010. This diagram also illustrate SharePoint 2010 as three tier Architecture:

SharePoint 2010 Technology Stack

 This diagram refers to SharePoint 2010 deployment in Production Environemnt. This Operating System includes also Win7 and others depending on the deployment.

Here is the explanation of some of these components:

• Windows Server 2008 or Windows Server 2008 R2 provides the core operating system functionality,
including the security subsystem.
• The Microsoft .NET Framework provides the framework for SharePoint, which is a .NET application
running within Internet Information Services (IIS).
• SharePoint Foundation 2010 provides fundamental SharePoint functionality including service
management, security, integration with Microsoft Office client applications, and core collaborative
features such as lists and libraries.
• SharePoint Server 2010 builds on SharePoint Foundation, adding social networking, enterprise search,
business intelligence, and other features.
• SharePoint content is stored in Microsoft SQL Server.

Error while Configuring Managed Accounts in SharePoint 2010

I got a strange error while creating Managed Account. I was creating the managed account with Automatic Password Change enabled. The Managed Account did not get created and it has given the below error:

"Access denied.  Only machine administrators are allowed to create administration service job definitions of type: Microsoft.SharePoint.Administration.SPGeneratePasswordJobDefinition, Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c."

 Now when I was trying to access the link of Configure Managed Account from Central Administration it is giving following error continuously:

"Object reference not set to an instance of an object."

On checking the ULS logs it tells:
"System.NullReferenceException: Object reference not set to an instance of an object.  
 at Microsoft.SharePoint.ApplicationPages.ManagedAccountsDataSourceView.FillDataTable(DataTable table, DataSourceSelectArguments selectArguments)   
 at Microsoft.SharePoint.WebControls.DataTableDataSourceView.Select(DataSourceSelectArguments selectArguments)   
 at Microsoft.SharePoint.WebControls.AdministrationDataSourceView.ExecuteSelect(DataSourceSelectArguments arguments)   
 at System.Web.UI.DataSourceView.Select(DataSourceSelectArguments arguments, DataSourceViewSelectCallback callback)   
 at System.Web.UI.WebControls.DataBoundControl.PerformSelect()   
 at System.Web.UI.WebControls.BaseDataBoundControl.EnsureDataBound()   
 at System.Web.UI.WebControls.CompositeDataBoundControl.CreateChildControls()   
 at System.Web.UI.Control.EnsureChildControls()   
 at System.Web.UI.Control.PreRenderRecursiveInternal()   
 at System.Web.UI.Control.PreRenderRecursiveInternal()

 at System.Web.UI.Control.PreRenderRecursiveInternal()   
 at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)"

So I was bit curious what is the issue and how to solve it. I could not find why this is happening but here is the workaround of the issue.
1. First remove the managed accounts which are created with Automatic Password Change. We need to use PowerShell for this. The cmdlet to delete the managed account is Remove-SPManagedAccount -I "sp2010\spadmin"

2. Now create the Managed Account and make sure do not select the Automatic Password Change Setting.

3. Now if you need to configure Automatic Password Change Setting go and edit the managed account and change the settings. Strangely SharePoint will accepts this.

Using SharePoint 2010 Web Analytics Feature with MOSS UI sites in SP2010

We have created a site collection in SharePoint 2010. There were some features which were not upgraded to 2010 in our site so we were using MOSS V3 master page. We need to use the new Web Analytics Feature of SP2010 but these options are not visible when the site uses the 2007 UI.
As a workaround we can enable the SP2010 experience from the Site Actions menu -- Look and Feel -- "Title, description, and icon" option as below:

We need to make sure that we select the option "Preview the updated user interface option". Make sure not to select the "Update the User Interface" option. With the preview mode the Web Analytics option started to appear in the Site Settings page. Now once we are done we can always go to the old user interface. Only trouble with this is that while we are in preview mode the site is displayed with the updated UI so some of the customization done will be broken for the time being when the site is in preview mode.
