Programmatic way to find application that is blocking port creation

To run some simulator we installed Windows Services for Unix. This uses an UDP port 1035,

In some PC's this Windows service for Unix works fine, but in others it fails. After some analysis I found that this is due to some Security application.

Now, this applicatio开发者_开发知识库n will be installed in 100s of PCs and most of them with various security application.

I would like to write a tool that would find the application that blocks the UDP port creation.

Is it possible?

You don't need to write a tool. netstat will tell you.
