I recently installed the IIS Security Patch labeled "Patch for Canonicalization Error Issue" (Knowledge Base article #Q269862) because a friend got the Sad Mind Virus because he didn't have this patch. The problem is that now when I publish my pages I can only view the HTML pages through my browser. If I try to view an .asp page through the browser I get a "Page Cannot be Displayed" error. I'm not positive that the patch caused this, but everything worked before and the patch is the only thing I can think of that is different. Any thoughts? Thanks.
