To list all the process running on port 8080 do the following      netstat -ano   find  8080    TCP    0 0 0 0 8080           0 0 0 0 0              LISTENING       10612  TCP         8080                   0                 LISTENING       10612   Then to kill the process run the following command     taskkill  F  PID 10612

If anyone is looking for a Powershell Script   function Search-And-Destroy       param    Parameter Mandatory  true   string  port        lines   netstat -a -o -n   findstr  port      ports            ForEach  line In  lines                 res      lines -split   s             ports     res 5              ports    ports   select -uniq      ForEach  port In  ports                echo   taskkill  F  PID  port            This function basically does what the above functions do  but it is in the Powershell scripting format so you can add it to your Powershell profile  To find your profile s location go to powershell and type echo  profile

Thank you all  just to add that some process wont close unless the  F force switch is also send with TaskKill  Also with  T switch  all secondary threads of the process will be closed    C   gt FOR  F  tokens 5 delims     P IN   netstat -a -n -o     findstr  2002   DO TaskKill exe  PID  P  T  F    For services it will be necessary to get the name of the service and execute      sc stop ServiceName

Using Merlyn s solution caused other applications to be killed like firefox  These processes were using the same port  but not as a listener   eg   netstat -a -n -o   findstr  8085   TCP    0 0 0 0 8085           0 0 0 0 0              LISTENING       6568   TCP    127 0 0 1 49616        127 0 0 1 8085         TIME WAIT       0   TCP    127 0 0 1 49618        127 0 0 1 8085         TIME WAIT       0   Therefore  can excluded these by adding  LISTENING  to the findstr as follows   FOR  F  tokens 5 delims      P IN   netstat -a -n -o    findstr  8085  LISTENING   DO TaskKill exe  PID   P

Just for completion   I wanted to kill all processes connected to a specific port but not the process listening  the command  in cmd shell  for the port 9001 is   FOR  F  tokens 5 delims     P IN   netstat -ano    findstr -rc   9001    ESTA    DO TaskKill  F  PID  P   findstr    r is for expressions and c for exact chain to match       is for matching spaces   netstat    a -  all n -  don t resolve  faster  o -  pid   It works because netstat prints out the source port then destination port and then ESTABLISHED

Similar to Merlyn s response  but this one handles these cases as well    The port number is actually a left substring of another longer port number that you re not looking for   You want to search for an exact port number so that you do not kill a random  innocent process  The script code needs to be able to run more than once and be correct each time  not showing older  incorrect answers    Here it is   set serverPid  for  F  tokens 5 delims      P in   netstat -a -n -o    findstr  E  8080    do set serverPid   P if not   serverPid             taskkill  PID  serverPid    else     rem echo Server is not running

Steps    Go to conf folder of your apache tomcat server  In my case its apache-tomcat-7 0 61 conf as I am using apache-tomcat-7 0 61 Open server xml and change the port number from 8080 to any other port as your wish  For example 8081 8082 8087 etc Now go to bin folder and run shutdown bat Now restart the server through eclipse     Now your project will work without any interruption

If you want to kill the process that s listening on port 8080  you could use PowerShell  Just combine Get-NetTCPConnection cmdlet with Stop-Process   Tested and should work with PowerShell 5 on Windows 10 or Windows Server 2016  However  I guess that it should also work on older Windows versions that have PowerShell 5 installed   Here is an example   PS C   gt  Stop-Process -Id  Get-NetTCPConnection -LocalPort 8080  OwningProcess  Confirm Are you sure you want to perform the Stop-Process operation on the following item  MyTestServer 9408    Y  Yes   A  Yes to All   N  No   L  No to All   S  Suspend      Help  default is  Y

Here s a command to get you started   FOR  F  tokens 4 delims      P IN   netstat -a -n -o    findstr  8080   DO  ECHO TaskKill exe  PID   P   When you re confident in your batch file  remove  ECHO   FOR  F  tokens 4 delims      P IN   netstat -a -n -o    findstr  8080   DO TaskKill exe  PID   P   Note that you might need to change this slightly for different OS s   For example  on Windows 7 you might need tokens 5 instead of tokens 4   How this works  FOR  F      variable IN   command   DO otherCommand  variable      This lets you execute command  and loop over its output   Each line will be stuffed into  variable  and can be expanded out in otherCommand as many times as you like  wherever you like    variable in actual use can only have a single-letter name  e g   V    tokens 4 delims      This lets you split up each line by whitespace  and take the 4th chunk in that line  and stuffs it into  variable  in our case    P    delims looks empty  but that extra space is actually significant   netstat -a -n -o   Just run it and find out   According to the command line help  it  Displays all connections and listening ports     Displays addresses and port numbers in numerical form    and  Displays the owning process ID associated with each connection     I just used these options since someone else suggested it  and it happened to work          This takes the output of the first command or program  netstat  and passes it onto a second command program  findstr    If you were using this directly on the command line  instead of inside a command string  you would use   instead of      findstr  8080   This filters any output that is passed into it  returning only lines that contain  8080   TaskKill exe  PID  lt value gt    This kills a running task  using the process ID     P instead of  P   This is required in batch files   If you did this on the command prompt  you would use  P instead
