What does "Can not obtain ownership information" in Netstat -ab mean?

Question

(Windows 7 x86)

If I run netstat -ab, I get a list of active connections, along with the names of the applications which have opened the connections.

However, some connections (including the one opened by my app) are listed as:

Can not obtain ownership information

Why?

Thanks,

Darren.

Answer 1

Run netstat -ano and look at the PID that it is under.

Answer 2

If you add the '-o' option, you'll see the PID values, and likely it will be PID 4, which is the System PID. This means it is probably a Service. (Note that Windows 7 will report "PID 4", while Windows XP will report "System").
