I seem to be lost exploiting a XP SP1 machine....

[Aarhem]

I don't know why I can't exploit this machine that I'm currently pentesting on... I was able to exploit my laptop a few weeks ago (which is running XPSP2) with ease but when it comes to my desktop I have no luck...

When I nmaped I got the following:
Interesting ports on 192.168.1.100:

No exact OS matches for host (test conditions non-ideal).
Network Distance: 1 hop

I know its a SP1 machine... And I tried several different exploits but they all keep failing... and autopwn didn't come up with a session either...

If anyone has any exploits/tips plz help a newbie out >.<!

Run a vulnerability scanner (nessus, openvas) against the system or check Microsoft KB articles or other vulnerability databases to see which vulnerabilities in the file sharing services affect XP SP1. Ensure you set your target as appropriate (to XP SP1) in Metasploit, if thats what you are using.

Also, stop using the term "pentesting" like that or I'm going to start ranting again.
