Welcome to the Q&A Forum

With regards to geotargeting, server location is irrelevant if you have the top-level domain - Google say so themselves (http://googlewebmastercentral.blogspot.com/2010/03/working-with-multi-regional-websites.html) - and there are plenty of UK businesses that successfully use a .com or other international domain, so a UK product doesn't have to belong on a .co.uk. Links (follow, at least) pass juice whatever country they're from, so having 100 US-based links will still help the overall authority of a website whether it's hosted in the UK, France, or anywhere. Are you saying the thousands of foreign links SEOmoz has, or the BBC, for example, don't help them rank so highly worldwide? Yes, country specific links are very useful to rank in that country, but other links help too. I think Rand mentions this as a pro in the video from the link in my previous post. There are plenty of companies who struggle to maintain one website, without even thinking about link building, so it's definitely a valid reason to consider keeping the one website. It is important to get it right first time. Weighing up the pros and cons can depend on a number of factors we haven't even mentioned, such as whether the site is e-commerce or not, for example. E.g. if someone from France sees a .it in the SERPs they might not click the link if other .fr links are there, due to the increased chance a .it might not ship to France.

I'm not to familiar with IIS myself, however I found a few good articles here on SEO Moz. You can also contact the author's of each post, I'm sure they know what to look for to fix it. http://www.seomoz.org/blog/what-every-seo-should-know-about-iis Additional Reading: http://www.seomoz.org/ugc/iis-case-folding-robots-and-results http://www.seomoz.org/ugc/iis-seo-issues
