xmlSocket on Flash player Version 8

I m currently developed an xmlSocket flash socket that connect to a php socket server.

Myserver was listening on “kent”, which is my PC name and my flash will connect to the server, ‘kent’ obviously on port 1025.

When I tried this on Flash player 9, it work perfectly but not in Flash player 8 (maybe below will also not functioning).

However, if I change the server listen on localhost, it worked fine on Flash player 8, the code like this:
socket.connect(“localhost”, 1025); // work fine in flash 8 and flash 9.
socket.connect(“kent”, 1025); // work fine in flash 9 but NOT flash 8.

Any idea what will be the issue here???

Thanks in advanced!!!
