Port scan from two machine

Hi everybody, m looking forward if somebody can answer my two queries
1>
if i scan my own computer from nmap (ofcourse not possible in windows) , will i get the ports from lo or local loopback also or just the ports from my ethernet card , the destination i have specified is the ip address of the computer itself.

2>
same way if i try to scan the same computer from other computer on network, i am getting different results,
Details
m/c 1: CentOS
m/c 2: Backtrack Live iso

wen i scanned for the centOS, from both, itself & Backtrack, i m getting different results,
while backtrack is showing port 38292(landesk) open, CentOS is showing much more ports
22
111
627
5555
5900
11111
16851

Both machines are on different subnets with inter subnet ping blocked, but i dont think so that should create a problem, as i m doing a syn scan on both.

Plz tell me what is the problem, Thanks in advance.
