IIS 5 - lockdown and urlscan installed on Windows 2000 server.  New firewall
put in place, webserver is on dmz and webserver is fully patched.

I rec'd this in my urlscan log - can anyone interpret this for me? I've
googled and read what I could find on this but am not sure if I should be
alarmed or if this is relatively normal.

"Received a malformed request which resulted in error 50 while modifying the
'Server' header. Request will be rejected with a 400 response."

Thanks in advance!
