Netstat Results in Windows XP

[pim]

When I type netstat -anbo I get
PC1
Active connections
Proto local address remote address State PID
TCP 0.0.0.0:135 0.0.0.0:0 LISTENING 1356
c:\windows\system32\WS2_32.dll
C:\WINDOWS\system32\RPCRT4.dll
c:\windows\system32\rpcss.dll
C:\WINDOWS\system32\svchost.exe

[svchost.exe]
PC2

c:\windows\system32\WS2_32.dll
c:\windows\system32\w32time.dll
ntdll.dll
-- unknown components --
[svchost.exe]

Why unknown components, is this a problema of -b option in the result of netstat or is there anything strange in these processes?
