Your server meets the requirements for this software. Nonetheless, there are some points you should take note of:

Windows IIS doesn't support URL rewriting by default. If you want the SEO advantages of rewriting you'll have to buy an IIS add-on product like ISAPI_Rewrite to enable the same functionality which Apache users get free. If you're not terribly concerned about URL rewriting, forget this -- you don't have to use rewriting.
Your web host's php.ini file has a low limit set for post_max_size. You will not be able to upload files larger than this limit. If you plan to host videos or other large user-contributed files you'll need to increase the limit.
