IIS restarts W3Svc when Creating new Virtual Directory from Default Web site

Question

Any ideas why MS in their infinite wisdom makes IIS 6 restart the W3C Service when I create an application/or virtual directory and then change the runtime version?

Thanks Mark

Answer 1

Whenever there is any change in the web.config or in virutal directory, application will be restarted and hence created sessions also expired Seven reason for application restart in Aspnet

best practice would be any change like you are doing, to down to application server by putting App_Offline.htm on root.
