We have setup an App Pool for each web application on our server. &nbsp;Everything has been working fine, but now we get Service Unavailable on each site. &nbsp;I check and the relevant app pool which the aplication being requested belongs to, stops with every request, thus showing Service unavailable.<br />
<br />
Soes any one know what conflict could be happening to cause the app pool to stop with every web request?<br />

IIS Service Unavailable

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.
