How can I tell what is listening on port 1000?

I need port 10000 on a Win2k3 server for Backup Exec 9.1 Remote Agent but it is already being used by some application.  (If I change it, I will have to change it on several dozen other servers that have BUE RA installed as well).  NETSTAT -a reveals the following:  

TCP    <ServerName>:10000    <ServerName>.<DomainName>:0    LISTENING
TCP    <ServerName>:10000    <ServerName>.<DomainName>:1038    ESTABLISHED
TCP    <ServerName>:10000    <ServerName>.<DomainName>:kpop    ESTABLISHED

How can I tell what application is using port 10000 so I can change it?

try netstat -o (will show you the pid - look for this in task manager)

otherwise download tcpview from www.sysinternals.com

netstat -ano will list all open and listening connections, their states and the PID that the program is using. You can then open task manager, go to view => select columns => check the pid box and then find the pid that you are looking for in netstat by looking for its port.

If there are loads of open ports (on servers etc) try netstat -ano > c:\netstat.txt and view it in notepad
