I've just found the following in my Apache logs:
Code:

Does anybody know what this request is supposed to achieve? It's several screens of these x04h and x90 characters, so DoS seems the most likely, yet it's a one-off thing.

It's an IIS attack - from either Nimda or Code Red - I don't remember which.

It's a scan for unpatched IIS machines. The requests are crafted such that IIS chokes on them and returns stuff it shouldn't, and it possibly executes code in the URL that it shouldn't, too.

Since you're using Apache, you can ignore those.
