help interpreting the nmap output

Hi,

I'm running nmap on Windows XP. Normally, it works fine (when I use it to scan a computer for which I know what services it's running) and returns detailed info on the services installed. However, I tried to run it on a web server on the Internet and I have trouble getting all the info.
Using -A -T4 options on a server and I receive the following reply

(The 1441 ports scanned but not shown below are in state: filtered)

Too many fingerprints match this host to give specific OS details

So, why the question marks next to the open protocols? Next I tried connecting to the telnet and ftp, but I get disconnected straight away. So I tried to get more info on the http and https by calling nmap with -sV -p 80 or -sV -p 443 options. Since it's a web server it is certainly running those services. I get something like

80/tcp    open   Apache httpd

Anyway, no sign of the Apache version. So, how can I find out what version of the Apache a server is running? What is the best way to proceed from here? TIA
