There are a couple things that you need to do to get Drupal running if you are using 1and1 for your hosting provider with clean urls.

• Download and copy the Drupal installation.
• Create a php.ini file with these two lines and copy it to the root of your site (…/mysite/)
  register_globals = off
  memory_limit = 16M
• Edit the .htaccess file and uncomment the line:
  RewriteBase /
• Add this line to .htaccess somewhere to enable php5
  AddType x-mapp-php5 .php

That should do it. Let me know if it doesn’t work for you in the comments.

I recently ran into an issue viewing a chm files in vista. Looks like chm files from untrusted sources are blocked by default. There is an easy fix though.

• Right click on the offending chm file
• Click properties
• Click unblock

The help file should open correctly now. If it doesn’t make sure you aren’t opening it from a network location. Chm files do not work on network shares. Just copy it local and follow the steps above.
