Http Error 503 The Service Is Unavailable On Localhost
all working fine until I installed some Microsoft updates including Windows 7 Service pack 1 when I started getting error 503 Service Unavailable.I posted a message on the Microsoft forum related to Windows updates, but all the suggestions for resolving or identifying the problem were unsuccessful. After uninstalling Windows7 SP1, turning off IIS Manager in 'Programs and Features' in the control panel,then turning on IIS with the default configuration, service unavailable iis Localhost appeared to be working correctly, and continued to work correctly after reinstalling Windows 7 SP1. I then reconfigured IIS to run PHP scripts following the instructions on http://technet.microsoft.com/en-us/library/dd239230(WS.10).aspx?ppud=4 but the error 503 returned. I have uninstalled PHP, turned off IIS, re-installed PHP and reconfigured IIS and still get the same error message. If I look in the 'Windows Logs/System section of 'Event Viewer' (in Control Panel/Administrative Tools'), I find 5 warnings and 1 error message all within a space of 2 seconds at the time I attempted to load the web page. The warnings ar all the same, and are Source: WAS Event ID: 5022 level: Warning Description: The Windows Process Activation Service failed to create a worker process for the application pool 'DefaultAppPool'.

is a common and frustrating problem that may occur for a number of reasons after a configuration change, or when deploying a new server machine. Another common "what the hell just happened" error is the plain 503 “service available” error that looks like this: Update: We recently launched a service that significantly helps you understand, troubleshoot, and improve IIS and ASP.NET web applications. If you regularly troubleshoot IIS errors, manage Windows Servers, or tune ASP.NET performance, definitely check out the demo at www.leansentry.com. What is it? This error is generated by the WAS (formerly W3SVC) service, which is responsible for creating IIS worker processes to handle incoming http requests. When WAS fails to create a worker process, it will generate this error. Why does it happen? There are a number of reasons why WAS may fail to start an IIS worker process. These include invalid application pool configuration, failure to create the process due to incorrect application pool identity settings, bad IIS configuration that causes the worker process to fail to initialize, or a process crash due to application logic. I will list the most probable reasons and how to investigate / fix them below. How do I get rid of it? Let’s get rid of it in 4 easy steps: STEP 1: Check whether your application pool is stopped Once WAS fails to start your worker process a set number of times, it goes into Rapid Fail Protection Mode and stops the application pool. This prevents application crashes from taking down the machine by going into a start process / fail loop when a persistent error exists. By default, Rapid Fail Protection is set at 5 times in 5 minutes. Once the application pool that contains your application has been stopped, all requests to applications in it will result in that plain 503 error. So, that’s the first thin
