This is interesting. Dan just said over MSN that he can't get to the site. Type this:
In IE, go to Tools, Internet Options, Security Tab. Click Trusted Sites, and add
http://www.monksdiner.com to the list of trusted sites.
Since I don't have this issue, I have no idea if it will work or not, but Dan also mentioned he couldn't see my blog which is on the same server, so I'm assuming it's IP block related. Give it a try and let me know if it works.
