    Foundstone.com has a useful tool called fport that will identify the pid
    on nt & 2k. Might be useful in this case.

    In XP you can type NETSTAT -o and this will show the PID of each
    connection. You can then use task manager to corrolate the PID against
    what program is
    running.   So NETSTAT -a -o will show you all listening processes and
    what
    PID is associated with them.

    Tomas,
    
    1025 is dynamically assigned, so really any program can request use of
    it. I have seen nterm use 1026 rather frequently.  1036 is usually an
    outbound port.
    
    You can see what all is listneing on your system by running netstat -l
    (unix) or netstat -a (windows) from a command prompt.

    I get constant alerts from Zonealarm and it is always blocking on ports
    1025, 1026, 1027 or 1029. Can someone tell me why?
    
    Sometimes also alerts from blocking on port 1036. What's there?
    
    TIA
    Tomas
