Not to sound snotty, but I've been watching this debate for a while here..

Alright,

Firstly -- Kiddies aren't going to have 0-day. And Kiddies are exactly 
who would be fooled by a simple port change.  A port change isn't going 
to fool me. I assure you it's only going to fool the lowest of the low..

Secondly -- 0-day comes out? That's the whole reason it's called 0-day. 
The whole concept is the exploits based on vulnerabilities not yet 
released. See, if a 1-day comes out, usually, if the author of said 
software is worth his salt, he's fixed the code as most likely he's been 
informed of his error.  Even if he hasn't. Someone has tapped him on the 
shoulder and I assure you he'll be fixing it soon or if MS, releasing a 
patch within 30 days. ;-)

Thirdly, I have to agree. This change is so basic, there's no reason to 
do it whatsoever. The problem is that most programs automagically grab 
banners these days, if fed the right options (nmap for instance) and 
your fooling no one. It's not as if the server doesn't respond with a 
fairly detectable banner in it's default configuration.You might as well 
paste a wig and fake moustashe on your server. :)

Changing the port on such a well documented and fingerprinted service, 
is nothing more than security through obscurity.

These are not the droids your looking for.
