How do I free my port 80 on localhost Windows?

Question

I installed XAMPP 1.6.8 and for some reason it didn't work. Later realized port 80 is not free or not listening. How can I release it or make it free?

Thanks a lot!

Solution 1

That agony has been solved for me. I found out that what was taking over port 80 is http api service. I wrote in cmd:

net stop http

Asked me "The following services will be stopped, do you want to continue?" Pressed y

It stopped a number of services actually.

Then wrote localhost and wallah, Apache is up and running on port 80.
Hope this helps

Important: Skype uses port 80 by default, you can change this in skype options > advanced > connection - and uncheck "use port 80"

Solution 2

netstat -ano

That will show you the PID of the process that is listening on port 80. After that, open the Task Manager -> Processes tab. From the View -> Select Columns menu, enable the PID column, and you will see the name of the process listening on port 80.

Solution 3

I had this problem previously,

if you see the Task manager(after enabling the view for PID), you will find PID=4 is "port 80 in use by NT Kernel & System; "

Just go to

1. Control Panel
2. Programs
3. Turn Windows features on/off
4. check if the World wide web services under IIS is checked

If so, Uncheck and netstat(or TCPVIEW) again to see if 80 is free.

Solution 4

netstat -a -b

Should tell you what program is bound to port 80

Solution 5

use netstat -bano in an elevated command prompt to see what apps are listening on which ports.

But Usually following applications uses port 80 in windows.

1. IIS
2. World Wide Web Publishing service
3. IIS Admin Service
4. SQL Server Reporting services
5. Web Deployment Agent Service

Stop above applications if running and check!!!

No I dont have an IIS. I did use xampp before and it had worked. I guess some other service is sitting on port 80 and not allowing the re-install of Apache service on it.

[Admin]

it just gave me bytes , unicast etc etc. did not give what is bound on port 80. Did I miss anything?

My xampp Application status shows both apache and mysql state 1 start 1 service 1 But the browser still does not show up the localhost. why so? any pointers? :(

Skype also likes to steal port 80, a common unexpected culprit!

[Vladimir Shmidt]

thanks, for me it was SQL Server Reporting Services (MSSQLSERVER) don't know why but when i terminate it by services console, process with pid 4 unbinded from 0.0.0.0:80

[Sundeep]

This is good as there can be other processes with the same name. I am wondering if there is any kill command in windows that I can run against the found PID instead of doing it via task manager.

[Philipp]

Win7: start-menu searching for "IIS" brings up the "IIS manager", where you can disable the server.

On Windows 7, I couldn't stop the processes due to "access denied", but it showed me names of the processes that would be killed if I had the rights (I didn't have rights for netstat -a -b).

[MoFarid]

@PavelV. you should run command prompt with administrative rights. open start, and write in search "cmd" right click on cmd and select Run as administrator.

[rahoolm]

Do you know by any means how to make sure that these services do not use port 80?

[Aravinda]

or you can use findstar in a batch file windowstechinfo.com/2015/05/…

I tried this and it said "the requested operation requires elevation"

[Aakash Thakur]

taskkill doesn't kill the task. Its still showing port 80 running. @Jijo

[Jijo]

can you try using /f /t at the end, it will forcefully kill the task, i am currently on a linux system, not verified

[divy3993]

You are GOD! Bowing Down, by this I was able to find the actual service name that had same Process ID with others, so couldn't figure out before the actual service to kill from task manager. Really Thanks!

[borat]

Thank you, this fixed my problem. "SQL Server Reporting Services" was using port 90 for me as well.

[winklerrr]

For me it says: can not obtain ownership information - what now?

[Bcktr]

Dafuq it works, I have been stopped all HTTP services but still denied using 80 port. Now it's worked after check manually services Thanks a lot dude, god bless you

the answer is irrelevant This question is about opening a port not vpn connection.

This worked for me. I was trying to use nginx on windows and it wouldn't bind giving a nginx: [emerg] bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket in a way forbidden by its access permissions) error. There are lot of fixes mentioned online, but this was the most straightforward one. Did require a reboot for me.
