How to Metasploit Framework Help

Hello,

I am exploiting a vulnerability.

http://gyazo.com/2c008d2f8dc654b1ca446ab4b58e28ec

So, I scanned the website first with Nikto. It brought out a vulnerability called MS99-025. So, I went towards Metasploit, started it and typed:

use exploit/windows/iis/msadc

Then, I set the RHOST: 127.0.0.1 (Example).

After I did all that, I typed in "exploit".

But, when I typed in exploit, it was all going fine, but it doesn't show any leakage.

Please tell me what could happen that nothing came up. The Gyazo shows that it didn't show anything.

Thanks,

R00T
