This code only works on XP and Server 2003. See the following
link for a function used in the code:

http://msdn2.microsoft.com/en-us/library/aa365804(VS.85).aspx

OP already said they have a solution for XP/2003.

thanx yar ...
here's the code that i have used to get the Process & Port combo's this
is
the C code which can be converted to a DLL to be used in Java
most of the code in it is commented as it was the extra information that
i
did not need
.
