As I said in a previous post, I am in the process of securizing a
group of sqlservers.

After finishing a SQLServer installation, I noticed that UDP port 1434
was listening on the machine. I did some researches about that port
and it seems it is used to map TCP ports to instance names. This port
would then act similarely to the RCP Portmapper.

I dont want this port to be openened since my unique db client is an
asp server and that this asp server always "know" the tcp port (the
port is hardcoded within the asp code).

So my questions are:

1. Did I correctly understand the usage of UPD 1434?

2. How can I shut it down?

3. If it cannot be shut down (that would not surprised me), how can I
change it?

thank you
