I'm a newbie in Java EE 7.

I have Netbeans 7.4 with GlassFish 4.0 and Java EE 7. In a 64-bit Windows 8.1 Pro machine. I want to start the GlassFish 4.0 Server, so I clicked on the services tab in Netbeans and then in the Servers option I right-clicked GlassFish Server 4.0 and then clicked Start.

When I did that I got the following message: "Could not start GlassFish Server 4.0: HTTP or HTTPS listener port is occupied while server is not running". I have also the IIS server, but I stopped it. After stopping IIS I tried to start again the GlassFish but it showed me the same message.

Also there is a window in Netbeans called **Output - Java DB Database Process** and it showed me the following:

```
Tue May 06 22:03:11 GMT-05:00 2014 : Security manager installed using the Basic server security policy.
Tue May 06 22:03:11 GMT-05:00 2014 Thread[main,5,main] java.io.FileNotFoundException: D:\Users\Juan Jose\.netbeans-derby\derby.log (Access is denied)
Tue May 06 22:03:12 GMT-05:00 2014 : Could not listen on port 1527 on host localhost:
 java.net.BindException: Address already in use: JVM_Bind
Tue May 06 22:03:12 GMT-05:00 2014 : Could not listen on port 1527 on host localhost:
 java.net.BindException: Address already in use: JVM_Bind

```

I ran a netstat -a in Windows to see what was happening with the 1527 port and that port is in LISTENING mode.

So how can I know what application or process is ocuppying the 1527 port?

Thanks for your help !!
