Hi,

the article gives a good idea of how to start -

an asp.net webserver is not really that different than a asp or static
webserver -

the ultimate reference for me still is :

securing windows nt/2000 for the internet by stefan norberg (o'reilly)

but i totally disagree with enabling automatic update on a web server -
who tells you that your dns is not poisoned - maybe you get updates you
don't want and these are installed automatically - i prefer checking the
certificate of a hotfix oder a service pack by myself before installing
it.

Basically you'll treat an asp.net application server as you would an asp
application server , which you've more or less done already. Theres a
good article on some potential issues at:
