Really high number of failed requests

What is going on...Really high number of failed requests.

[websiteseo]

Hello.

A friend on mine just converted their site from a standard .html site to a .cfm site and now all hell is breaking loose.

The first thing they noticed was their page rank disappeared and the positioning dropped. Then they noticed that the log file and all of the failed requests.

Here is a copy of what they are seeing. I removed the URLs. I hope that is okay. Can anyone shed some light on this?

Program started at Tue-21-Mar-2006 08:01.
Analysed requests from Tue-14-Mar-2006 00:00 to Mon-20-Mar-2006 23:57 (7.00 days).

Listing the top 30 referring URLs by the number of failed requests, sorted by the number of failed requests.

reqs: URL
-----: ---
19973: [domain.com...]
7729: [domain.com...]
<snip>
430: [domain.com...]

10281: [not listed: 110 URLs]

Thank you SOOOO much for your time! Any help will be greatly appreciated!

It would be more useful to look at the raw server error log to identify this problem. The referring URLs are quite likely to be irrelevant to the root problem, since there are so many. The server error log may tell you exactly what is wrong.
