Http Error : 503. The service is unavailable. SharePoint Central Administration and SharePoint WebApplication

Hi All,

Last Friday , I ran Windows Updates on my Machine. and then ran my SharePoint Site and faced an error "Http Error : 503. The service is unavailable."(See the snapshot below).

I run a headache looking into a solution of this problem, tried restarting all services, sql server and even rebooted my machine serveral times. And after which I found that the Application Pool of all sites was stopped. I started the Application Pool for SharePoint Admin and Other SharePoint WebApplication, and things went fine as usual.

Go to IIS, Application Pools and start the Application Pool one by one of each application.(See the below snapshot)

My Machine Specs: Windows Server 2008 R2, Sql Server 2008 R2, SharePoint Server 2010, Visual Studio 2010

Hope this solution will solve your problem.

Thanks,

Differences Between Sandboxed and Farm Solutions

Hello everybody,

This blog post is for all those guys who are new to Microsoft SharePoint Technologies and want a precise concept of what are Sandboxed solution and Farm Solution.

The MSDN explains it brilliantly......

Here is the URL : http://msdn.microsoft.com/en-us/library/ee361616.aspx

Below is the content from MSDN :

When you compile a SharePoint solution, it deploys to the SharePoint server and a debugger attaches to debug it. The process used to debug the solution depends on the setting of the Sandboxed Solution property: sandboxed solution or farm solution.

Farm Solutions

---

Farm solutions, which are hosted in the IIS worker process (W3WP.exe), run code that can affect the whole farm. When you debug a SharePoint project whose Sandboxed Solution property is set to "farm solution," the system's IIS application pool recycles before SharePoint retracts or deploys the feature so as to release any files locked by the IIS worker process. Only the IIS application pool serving the SharePoint project's site URL is recycled.

Sandboxed Solutions

---

Sandboxed solutions, which are hosted in the SharePoint user code solution worker process (SPUCWorkerProcess.exe), run code that can only affect the site collection of the solution. Because sandboxed solutions do not run in the IIS worker process, neither the IIS application pool nor the IIS server must restart. Visual Studio attaches the debugger to the SPUCWorkerProcess process that the SPUserCodeV4 service in SharePoint automatically triggers and controls. It is not necessary for the SPUCWorkerProcess process to recycle to load the latest version of the solution.

Either Type of Solution

---

With either solution type, Visual Studio also attaches the debugger to the browser to enable client-side script debugging. Visual Studio uses the script debugging engine for this purpose. To enable script debugging, you must change the default browser settings when you are prompted.

Visual Studio attaches the debugger only to the W3WP or SPUCWorkerProcess processes running the current site. Visual Studio also attaches the managed COM Plus and workflow debugging engines.

All about Sanboxed Solution , below is the link from http://technet.microsoft.com

I hope the above links will make you clear differences between Sanboxed and Farm Solution in SharePoint.

Have a great day.!

Thanks,

System.Windows.Xps.Packaging - Reach Framework => Add reference DLL
