I have a Windows 2008 R2 server that will need to listen on a particular port (e.g. 1234) in order for an application upgrade to work, but currently the application doesn't have a listener service configured for port 1234.
Our firewall is managed by a third party, but I would like to check in advance that the port 1234 has been opened before I install the update. Is this possible?
I know I can telnet to the server on other listening ports, but as this server has no application listening to 1234 I can't be certain that it is in fact, open. Telnet results are inconsistent when connecting to ports that are apparently listening in netstat.
Is there anything I can do in Powershell or VB for instance, to set up a listener for port 1234 in advance of the upgrade to ensure it will go smoothly?
Many thanks in advance.
Anything that accepts traffic would work.
Run some other service on port 1234 and see if you can connect to that.
Use a network sniffer like WireShark on the server and see if you're getting connection attempts to port 1234.
Install netcat on the server and tell it to listen to port 1234 then connect to that port on the firewall. If it connects, the port is open. (This is really the same as #1 but without an actual service.)
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!
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.
Important: Skype uses port 80 by default, you can change this in skype options > advanced > connection - and uncheck "use port 80"
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.
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
Control Panel
Programs
Turn Windows features on/off
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.
netstat -a -b
Should tell you what program is bound to port 80
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.
IIS
World Wide Web Publishing service
IIS Admin Service
SQL Server Reporting services
Web Deployment Agent Service
Stop above applications if running and check!!!
Use TcpView to find the process that listens to the port and close the process.
Other option to try is to stop SQL Server Reporting Services.
You can use net stop http it will display which process is using. Moslty world wide web services are using
Try
netstat -anb -p tcp
that show ports and processes
I was trying to install nginx from here - http://nginx.org/en/docs/windows.html
Going to http://localhost/ will show something, at least a proper "not found" message
This is because 80 is the default port, and it was taken by other processes.
Now run below command:
net stop http
// Above command stopped below services
// - SSDP Discovery
// - Print Spooler
// - BranchCache
// - Function Discovery Resource Publication
// - Function Discovery Provider Host
Now, going to http://localhost/ will fail with a broken link page message.
Main process was BranchCache
This process, after stopped, will restart in a few seconds.
So we need to run other commands we need soon, an example below:
// this will stop
net stop http
// immeidately run other command you want to
start nginx
Now, going to http://localhost/ gave me:
Welcome to nginx!
Hope that helps.
Type in "netstat -ano" into your command line. I saw that it was showing something for Local Address port 0.0.0.0:80.
My issue was because I had SQL Server Reporting Services on Port 80. So I followed these instructions and changed the port # from 80 to 81:
http://seankilleen.com/2012/11/how-to-stop-sql-server-reporting-services-from-using-port-80-on-your-server-field-notes/
Here is a picture of my command line AFTER I changed the port number for SQL Server Reporting Services:
If you are still having the same issue, read this forum:

This is just a guess, but since port 80 is the conventional port for HTTP, you may have a webserver running on your system. Is IIS active?
If you are running IIS you may have the web farm service running. That was what was killing my xampp.
Skype likes to use port 80 and blocks IIS. That was my prob.
I also had the same problem. net stop http didn't help and World wide web services option under IIS in Windows Control Panel was unchecked. So in XAMPP control panel I just checked the Svc checkbox near Apache start button (Install Apache as service) and rebooted Windows. And now each time Windows starts Apache is started automatically and occupies port 80 before any other service does. Worked for me!
Known Windows Services That Listen on Port 80
From Services Manager (run: services.msc), stop and disable these Windows Services which are known to bind to port 80.
Double click Service, and change ‘Startup Type’ to ‘Disabled’…
SQL Server Reporting Services (ReportServer)
Web Deployment Agent Service (MsDepSvc)
BranchCache (PeerDistSvc)
Sync Share Service (SyncShareSvc)
World Wide Web Publishing Service (W3SVC)
Internet Information Server (WAS, IISADMIN)
skype also using port 80 as default setting and you can uncheck it.
You might, or might not, have some of these Services installed and running.
In my case "SQL Server Reporting Services" was opening port 80.
Identify the real process programmatically
(when the process ID is shown as 4)
The answers here, as usual, expect a level of interactivity.
The problem is when something is listening through HTTP.sys; then, the PID is always 4 and, as most people find, you need some tool to find the real owner.
Here's how to identify the offending process programmatically. No TcpView, etc (as good as those tools are). Does rely on netsh; but then, the problem is usually related to HTTP.sys.
$Uri = "http://127.0.0.1:8989" # for example
# Shows processes that have registered URLs with HTTP.sys
$QueueText = netsh http show servicestate view=requestq verbose=yes | Out-String
# Break into text chunks; discard the header
$Queues = $QueueText -split '(?<=\n)(?=Request queue name)' | Select-Object -Skip 1
# Find the chunk for the request queue listening on your URI
$Queue = #($Queues) -match [regex]::Escape($Uri -replace '/$')
if ($Queue.Count -eq 1)
{
# Will be null if could not pick out exactly one PID
$ProcessId = [string]$Queue -replace '(?s).*Process IDs:\s+' -replace '(?s)\s.*' -as [int]
if ($ProcessId)
{
Write-Verbose "Identified process $ProcessId as the HTTP listener. Killing..."
Stop-Process -Id $ProcessId -Confirm
}
}

I faced the same issue and fixed it by making a small change in the httpd.conf file which can be obtained by clicking the config button along with the Apache option.
The change I made was to replace listen 80 with listen 8080.
For me, this problem began when I hosted a VPN-connection on my Windows 8 computer.
Simply deleting the connection from "Control Panel\Network and Internet\Network Connections" solved the problem.
Did some google on it and the solution was to redirect using iptables or mod in apache? Since my application uses websockets the above solution breaks my websocket connectivity and I again have to connect to my websockets using port 8080. Is there any way that I can run the glassfish itself on port 80 so that my websockets also run on port 80 making easier for users behind corporate firewall to access the app since corparates may block 8080.
I have root access as well.
To run GlassFish on port 80 you need to :
Connect to the administration interface (by default on port :4848)
In the left menu go to Configurations
Then select the appropriate configuration you need to change eg server-config
Then go to Network Config
Then go to Network Listeners
Select the appropriate listener, probably http-listener-1
Change the Port value to 80
Save and reboot your GlassFish server/instance/cluster according to your needs
Using the command line utility
asadmin set configs.config.server-config.network-config.network-listeners.network-listener.http-listener-1.port=80
you may need to replace server-config and/or http-listener-1
Go to glassfish4\glassfish\domains\domain1\config folder and here open domain.xml file
and find tag
<network-listeners>
<network-listener port="9999" protocol="http-listener-1" transport="tcp" name="http-listener-1" thread-pool="http-thread-pool"></network-listener>
</network-listeners>
in port attribute of <network-listeners> you can specify your port address whichever you want.
Here's another approach.
You can go to the admin console under port 4848 (I am using Glassfish 4.1.2) and navigate to "Configuration" > "server-config" > "HTTP Service" > "Http Listeners" > "http-listener-1" in the left hand navigation.
Click on the "http-listener-1" link in the main content window.
Change the port to desired number and save.
Restart Glassfish and run your application.
in some cases you have to change port before glassfish is started (in my case port 8080 is already in use by another instance) so answer 4 worked for me.
Following are simple steps to change the port number of Glassfish server (GlassFish runs by default on port number 8080):
Go to the folder where Glassfish is installed.
Locate config folder which is as follows (Windows):
C:\Program Files\glassfish-3.0.1\glassfish\domains\domain1\config
Open domain.xml using any text editor.
Look for 8080 and change it to some other port number that doesn’t conflict with other port numbers (e.g. 8081).
Save domain.xml.
Additional step if necessary:
Now remove GlassFish from IDE and add it again so that IDE understands the new port number.
Restart GlassFish, if it was already running.

I have a very strange problem with my Apache 2.4 working with Xampp 1.8.2 on Windows Server 2008 R2.
When I tried to start Apache server in XAMPP, an error message is shown:
[Apache] Problem detected!
[Apache] Port 443 in use by "Unable to open process" with PID 4!
[Apache] Apache WILL NOT start without the configured ports free!
[Apache] You need to uninstall/disable/reconfigure the blocking application
[Apache] or reconfigure Apache and the Control Panel to listen on a different port
However, the process with PID 4 is system! I've tried to restart my computer and it doesn't work.
I have installed Apache 2.4 via a tar.gz file sereral days ago, and uninstalled it. So, I don't think this behavior will cause the problem.
And here's the result using commond netstat -a -n -o | findstr 443
C:\Users\Administrator>netstat -a -n -o | findstr 443
TCP 0.0.0.0:443 0.0.0.0:0 LISTENING 4
TCP [::]:443 [::]:0 LISTENING 4
Can you tell me what to do?
Just change the sll port in httpd-ssl.conf file. It would be under C:\xampp\apache\conf\extra.
Find "443" and replace it with other values(e.g 8181), then start your apache again
I had the same problem: port-443-in-use-by-unable-to-open-process-with-pid-4
First I disabled the weather tile in Win* that apparently phones home to Redmond for updates after this showed on netstat list.
This didn't solve the problem. I looked at the post already here which mentioned VPNs, so
I went to Control Panel\Network and Internet\Network and Sharing Center and clicked on Change adapter settings
I clicked on Incoming Connections and right clicked on properties
The VPN click box at the bottom of the General tab was on, so I unchecked it
Under Users, I also unchecked a previous user I had allowed to copy some data weeks before
Then I clicked okay
Closed the control panel and restarted the XAMPP control panel
It fired right up without a problem.
Similarly, I experienced this:
Port 443 in use by "Unable to open process" with PID 6012!
When starting XAMPP Control Panel v3.2.1 for the first time.
In Task Manager I found that PID 6012 was Apache web server.
A copy of it was running in the background without the GUI,
and when I invoked the GUI it was trying to start another copy.
Killed the phantom copy and then XAMPP started up fine.
I didn't have to change any port settings.

Simply run as Administrtor "xampp-control.exe"
I had the same problem. Another way to solve this problem when running XAMPP on Windows:
Open a CMD prompt and type in command:
net stop was /y
Run Dialog Box (press keys Win+R)
.. then type: services.msc
I then scrolled down to:
World Wide Web Publishing Service
Double clicked on it and clicked STOP (if this service status is Started)
3.Start Apache again with XAMPP :)
Link Ref: http://www.sitepoint.com/unblock-port-80-on-windows-run-apache/
Some process is using this port, so you can change the port that is used by xampp, to be able to use it.
For this job you have to do this:
1- Open httpd-ssl.conf in xampp\apache\conf\extra
2- Look for the line containing Listen 443
3- Change port number to anything you want. I use 4430. ex. Listen 4430.
4- Replace every 443 strings in that file with 4430.
5- Save the file.
Probably some process is using that port, i would guess you have another webserver running with ssl/tls already. You must trac down what process is using the port and shut it down. The fact that it does not help to restart your computer makes me think that you may find what you are looking for in msconfig. Try to have a look there, open prompt and write msconfig
post 443 is normaly used by secure http, => https
I have never used windows server but there could be some built in webserver that autostarts, have you ever installed another webserver?
Try use the command Netstat -a -n -o to see what process that is blocking. you can the process pid from the output.
The
Routing and RAS - service is your problem i guess look at this post
it does this, thats why its blocking:
SSTP tunneling protocol
Secure Socket Tunneling Protocol (SSTP) is a new form of virtual private networking (VPN) tunnel with features that allow traffic to pass through firewalls that block PPTP and L2TP/IPsec traffic. SSTP provides a mechanism to encapsulate PPP traffic over the SSL channel of the HTTPS protocol. The use of PPP allows support for strong authentication methods, such as EAP-TLS. The use of HTTPS means traffic will flow through TCP port 443, a port commonly used for Web access. Secure Sockets Layer (SSL) provides transport-level security with enhanced key negotiation, encryption, and integrity checking.
from tecsupport.ms
Below steps by sztupy worked for me
I went to Control Panel\Network and Internet\Network and Sharing Center and clicked on Change adapter settings
I clicked on Incoming Connections and right clicked on properties
The VPN click box at the bottom of the General tab was on, so I unchecked it
Under Users, I also unchecked a previous user I had allowed to copy some data weeks before
Then I clicked okay
Closed the control panel and restarted the XAMPP control panel
I simply went to the XAMMP config button in the XAMPP control panel GUI and clicked on Server and Port settings and I changed the SSL port value.
I had the same problem when I installed xampp on Windows 7. I installed Windows server and Web Deployment Agent Service (MsDepSvc.exe) which uses port 80. So I had an error PID 4 listening to port 80 when I ran apache.
Solution
Open task manager: (Ctrl+Shift+Esc) then find "MsDepSvc.exe" and disable it. Finally restart xampp
ref: http://www.honk.com.au/index.php/2010/10/20/windows-7-pid-4-listening-port-80-apache-cannot-star/
Here it was the "Work Folders" feature having been added on a Server 2012 R2. By default it is listening for HTTPS client requests on port 443 via the "System" process.
There is a Technet blog post explaining how to change that port number. Don't forget to add a corresponding firewall rule for your custom port and disable the existing one for port 443 though.
I got this same error and managed to fix it by closing Skype and running XAMP as Administrator, works perfectly now. So right click THE XAMP icon and click run as admin.
The port is being used by another process,
PID 4 means it is Windows System, you can open a cmd window with "super user/administrator" priviledges and write "net stop http", it will stop all the web services. Then check if it freed the port.
I had the same problem and it happened to be the "Routing and Remote Access Service". You open Services in the windows search, and then look for the specific service name. Change the startup of it to manual or automatic (whatever you decide).
Use some app like TCPView to help what port each App PID is using.
The origin of the problem seems to be Microsoft not knowing what the word disable Microsoft VPN means...
I ran task manager and looked for httpd.exe in process. Their were two of them running. I stopped one of them gone back to xampp control pannel and started apache. It worked.
I had the same problem and solved by doing following.
Go to Task Manager, click on services tab, order by pid's than if you find the related process, kill it otherwise, right click and click on show details, the process should be shown now. order by pid's than kill the related process.
I had this same problem with port 443, process id 4 and everything. For me it was not the VPN using the port, it was IIS. To fix this I opened up IIS and right clicked on my instance and stopped it. Then IIS Express(Or apache if you're using that) was able to use port 443. Hope this helps someone else.
I had a similar issue where port 443 was blocked by PID 4. After breaking my head for several hours I found the command netsh show urlacl which gave me an idea of the system process blocking the port.
To run command run cmd or windows shell in administrator mode.
netsh
http
show urlacl
I got response a which showed 443 was blocked by NT Service SSTPSvc Reserved URL
Response
https://+:443/sra_{BA195980-CD49-458b-9E23-C84EE0ADCD75}/
User: NT SERVICE\SstpSvc
Listen: Yes
Delegate: Yes
User: BUILTIN\Administrators
Listen: No
Delegate: No
User: NT AUTHORITY\SYSTEM
Listen: Yes
Delegate: Yes
With this information I followed the microsoft link to change the listening port for SSTP based vpn. https://support.microsoft.com/en-in/kb/947032
This resolved my port issue.
A simple way to fix this is to change the XAMP port to a random number.
The solution by "Mark Seagoe" worked for me too.
I got a message that "Port 443 in use by Unable to open process with PID 14508".
So i opened task manager and killed this process 14508. This was used by my previous xampp version and it was orphaned.
so no need to change any ports or anything, this is a simple two step process and it worked .
STEPS
Un-install apache(xampp) software from your windows.
Delete the xampp folder from c folder.
Delete the folder from recycle-bin to permanently delete the xampp folder
Restart your computer.
Finally install a clean copy of apache(xampp) software.

We are trying to run a wcf service with net.tcp binding using port 80. When we try to start the service we get error 10013.
The service worked fine on port 8099 untill operations blocked the port :)
Our alternative is to switch to basichttpbinding.
What I am wondering is: Is there some fundamental reason why nettcp binding does not work with port 80.
Port 80 is probably being used already by IIS. You'd need to disable the websites running on that port.
Try checking if there's any application already using port 80, or try running it as administrator. Firewall rules can make this problem appear too.
See if it helps.
