<div>
I just worked it out myself.<br />
<br />
I was able to run IISState (<a href="http://www.iisfaq.com/default.aspx?view=P197" rel="ugc">http://www.iisfaq.com/default.aspx?view=P197</a>) on the server on a rare occation when it was unresponsive. It appears the problem on the web server could be caused by a bug in the jet database driver as mentioned here <a href="http://www.adopenstatic.com/cs/blogs/ken/archive/2005/05/11/18.aspx" rel="ugc">http://www.adopenstatic.com/cs/blogs/ken/archive/2005/05/11/18.aspx</a><br />
<br />
There is a Microsoft hot fix here <a href="http://support.microsoft.com/?id=838306" rel="ugc">http://support.microsoft.com/?id=838306</a><br />
<br />
The event logs don't show anything unusual and the web logs don't either as it is just random as to which script is the last one to run before the problem occurs.

I have a website on IIS6.0 that will occationally stop serving ASP pages yet still serve images. <br />
<br />
The IIS processes show 0 CPU use and the memory and handles are normal.<br />
<br />
When this happens we have been fixing it by restarting the IIS service. <br />
<br />
Is there any way to know why IIS is becoming unresponsive and stop it from happening?

IIS6 Unresponsive

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.
