I am using an application which needs to access to port 20000 on my domain
controller.
The problem is that sometimes port 20000 state changes to close and my
application stops functioning.
once I remote desktop to the server port state changes to open again and my
application works fine again.

any idea what is wrong?

thanks

Saeed,

Remember that the port will only be listed as open if the application is
actively listening on that port. It is possible that the application
stops or goes dormant when you are not logged in. When you are RDP'ed
in, the application wakes up again.

This is why (just one of the reasons) most applications that have to
listen on ports are configured as services. I would suggest that you
take this up with the application developer/ company.

There are a few other things that could be causing this, but I think
this to be the most likely. Other things to look at are the firewall
and conditional traffic handling on your network.
