>Do you have the Enable Default Document under the highest level web server folder checked under the Document properties (I am not talking about any subfolders you ahve created, make sure youc check the root folder for the Web Server)? If it is not checked and you try to access the Web Server with just http://999.999.999.999/ you will get an error page as there is no default document for the root. Are you trying to access just the IP or the IP with a page (e.g. http://999.999.999.999/mypage.asp)?

Yup I have a default document on the root folder. And I try access just the IP as well as with the page name too. Same 404 error.

P.S. I work for VGH in Biomedical Engineering.
