intermittent problems with missing page components and connection error 10061

[fdr]

Hi

I have an intermittent problem that some page components ( images, systel sheets) sometimes are missing in the server response.
In a  few cases the browser even shows an error page with error code 10061.

My environment is windows server 2003, iis 6.0, mysql 5.0.41, php 5.2.2.

I wonder if this are the symptoms of performance problem and something times out depending on the server load?
Did anybody see similar problems? Where to look for diagnostics? Any Ideas? Any tuning required?

Thanks

Hello,

may be you should use less Microsoft specific software and error messages. I suggest you install Firefox with its webdeveloper toolbar, point it to your site, and tell us what "Information"->"View Response Headers" shows so we can try to diagnose.

After having discovered (with the Firefox web dev tool) that all the problems are related to error 10061 ( connection refused ) I ultimately followed your advice quoted above and switched to apache. This solved the problem -  and the site as well as access to the cmsms front end are MUCH faster now.
Apparently IIS runs into memory problems and starts to refuse connections ( admittedly there is a lot of other stuff running on this box).

Thanks
