IIS Service Unavailable

We have setup an App Pool for each web application on our server.  Everything has been working fine, but now we get Service Unavailable on each site.  I check and the relevant app pool which the aplication being requested belongs to, stops with every request, thus showing Service unavailable.

Soes any one know what conflict could be happening to cause the app pool to stop with every web request?

How many application pool do you have on IIS? I think the following MS KB should help you :

Clients receive a "service unavailable" error message in their Web browsers when you run many application pools under separate identities in IIS

No unfortunately that was not the issue.  I have now sorted it and it was due to a conflict based on the Server Enviorment (64 bit/32bit) and a .NET Framework version conflict of some sort.

Either way though, thanks for your input.
