Yes. This is someone trying a IIS attack on your linux server. It will have no effect at all, other than cluttering your logs. The fact that time is not being taken to even profile the OS of their target shows that this attempt is likely just being automated on a range of ip addresses.

What I do is add this to httpd.conf:
Code:
 <IfModule mod_rewrite.c>
   RedirectMatch permanent (.*)cmd.exe(.*)$ http://www.microsoft.com
   RedirectMatch permanent (.*)root.exe(.*)$ http://www.microsoft.com
   RedirectMatch permanent (.*)\/_vti_bin\/(.*)$ http://www.microsoft.com
   RedirectMatch permanent (.*)\/scripts\/\.\.(.*)$ http://www.microsoft.com
   RedirectMatch permanent (.*)\/_mem_bin\/(.*)$ http://www.microsoft.com
   RedirectMatch permanent (.*)\/msadc\/(.*)$ http://www.microsoft.com
   RedirectMatch permanent (.*)\/MSADC\/(.*)$ http://www.microsoft.com
   RedirectMatch permanent (.*)\/c\/winnt\/(.*)$ http://www.microsoft.com
   RedirectMatch permanent (.*)\/d\/winnt\/(.*)$ http://www.microsoft.com
   RedirectMatch permanent (.*)\/x90\/(.*)$ http://www.microsoft.com
</IfModule>
Now these lamers are redirected to microsoft.com...
