I have an >Admin > Site Wizard (SW) problem on a production server.  The problem does not exist on my localhost development machine. The entire website functions well with the only exception being step 3 of the SW.

I am wondering if anyone might be able to provide shed some light as to a fix.

When I get to step 3 of the SW some, but not all of the 700 skin thumbnails load. It usually takes 4 or 5 attempts before all thumbnails load (i.e. loading more into the browser cache with each attempt). With <not all of the thumbnails loaded> page state; if I refresh the page or attempt to navigate away from the SW-Step-3 page I get the following errors:

===-===
IE: Internet Explorer cannot display the webpage
Chrome: The connection to www.mysite.com was interrupted
Safari: Winsock error 10054 is Connection reset by peer, or forcibly closed by the remote host.
Firefox: The connection to the server was reset while the page was loading
Opera: Connection closed by remote server
===-===

With this in mind, I am locked-out of entire website access for about 45-60 seconds with the above error messages.

My very helpful host has tried several server configs in my dedicated app pool with no success.

Any ideas as to a possible solution would be welcomed.

Thank you.
