Good day...

I've been working on a website project, that requires to be on a Microsoft IIS Web Server. It is HTML, pure HTML, with really nice CSS, web-standards, etc. I open this website using in my computer, using Firefox, IE 8.0, Safari, Google Chrome and it looks fine everywhere.

But as I upload it to the Microsoft IIS server, it changes a few things. for example:

the main menu, which is a navigation bar that has dropdowns, seems to change it's line-height for some reason, and it is bigger. Some <h3> or <h2> Alignment seems wrong as well...

And the lines that are supposed to surround the photographs in the website (like a frame - dotted line) won't appear. But all the rest of the CSS is loading perfectly fine. I don't think it's a path problem as everything is loading fine. But this is making me look bad and it is very important to have this done as soon as possible.

Can someone give me good suggestions on what to look at ?

The IIS permissions seem fine. I'm not a big Microsoft fan...but I have to develop the website there. Also, I uploaded the site to my apache server and it worked wonders. I wish I could change the policies in this corporation, but I can't. Thank you so much for your kind help.
