In 8.0.1.2 in our dev environment, we can select a product for editing in the admin site. But when we press the update button the request goes off to the server and eventually times out with the error: The connection was reset. The connection to the server was reset while the page was loading.

Looking in the IIS logs we get the following:
2011-04-28 09:27:10 /xadminx/entityEditProducts.aspx iden=2604&entityName=Category&entityFilterID=750 192.168.0.111 500 0 64

This doesn't show the same problems on our production admin site.

I've just un-installed and re-installed IIS on our dev server, but no change.

Any ideas?

Many thanks
