Setting up new IIS 6 servers can be a pain. The config is so daunting they call it a metabase! Backing up the metabase is super important, but did you know you can copy the entire metabase to another server? Yes you can, and its pretty awesome.
cscript iiscnfg.vbs /copy /ts ANOTHER_SERVER /tu domain\user /tp password
Perfect for web farms where you are adding new servers and need to script setup. It may not be as pretty as Apache or Lighttpd configs, but it works and saves hours of error prone setup.
