Actually, NMAP offers a decent method of identification on TWO factors: (1) identify the software running on the target server (if applicable), and (2) identify the version of the software.
The parameters are: nmap -A -T4 -F <target hostname or IP address>
If the site is blocking ICMP, try it with the "-P0" option.
