Hi buddies i m new to ASP.NET.While i'm hosting my website in IIS(Internet Information Service),I'm getting an error as in the below picture...what should i do to fix it?I gotta tired after struggled with my codes and a lot.
This means there is another application that is using port 80. If you change the bindings for the website to something other than 80 it will work.
You can also do the following to free up port 80:
Run NETSTAT -ano in command prompt and find out the PID for the process that is using port 80. Open up the task manager and in the Services tab find that PID to see what application it is.

I'm trying to set up a malware analysis lab, following the instructions found here:
https://blog.christophetd.fr/malware-analysis-lab-with-virtualbox-inetsim-and-burp/
In setting up inetsim to simulate internet protocols, I keep getting "http_tcp_80 - failed!" everytime I run it. Changing the port it uses in the configuration file to 8080 causes the it to work. When I run it on a different vm, the configuration works as intended.
I have apache also installed on this vm. Could it be interfering?
Edit: I just installed a new vm to try using inetsim without apache installed. HTTP is reported to be running, but now dns_53_tcp_udp is reported to be failing to start. Trying to browse web pages to bring up inetsim's default page fails, regardless of if I use the FQDN or the IP address. The only time I get the page is with localhost. Otherwise, I get server not found. At least I know its not apache.
The error I get with DNS indicates that the 0.0.0.0 ip is already in use, which doesn't make sense to me since 0.0.0.0 is being used to bind the services to all IPs. Changing the inetsim.conf file so "service_bind_address 10.0.0.0" instead of "service_bind_address 0.0.0.0" seems to run dns, but the browser on both the analysis machine and the victim machine still report no server found.
You should stop the Apache server:
service apache2 stop
It works for me.
I guess there are some other processes listening on those ports.
Use
sudo netstat -tulpn | grep LISTEN
It will print out those processes with their pid. For example, 964 is the pid of the first process in this case:
Check if something is occupying your corresponding ports. Shut them down with
sudo kill -9 <pid>
Of course, the busy processes running on those ports may not in listening states but still be able to cause such a problem. So you can check it with
sudo netstat -tulpn
just in case.
Anyway, it does work for me.
This is on Windows system. I have tomcat started on 8080. I have a nodejs program started which is also listening on 8080. So now I have 2 PIDs. When I do a netstat, I find two PIDs on the same port. So everything is clearly being shown. And these two processes ran without showing up any error. What baffled me is when I access the url localhost:8080 on the browser, it sometimes shows up tomcat home page and the rest of the time it shows up the nodejs response. Looks like there is a race between the processes as in whoever catches it first throws up a resonse. Next as I see that there is no error being thrown on reusing the same port, I try to open up another nodejs program listening on 8080. But this time it throws an error saying EADDRINUSE. This is confusing. If it had to throw such an error, why would it in the first place allow nodejs and tomcat both to listen on 8080? Any factual inputs and no conjectures would be helpful.
You either:
have a proxy in front of your servers
you run the servers on different network interfaces
some sort of port sharing has been setup on that machine.
Trying to set up a default website in IIS. When trying to start the website I get the error message: "website cannot be started another website may be using the same port."
I don't see any other bindings on port 80 in IIS. Is there a way to determine what else might be using the port on the machine?
Thanks
Ran across an issue like this when I was setting up a new web site on port 80. Of course, the Default Web Site instance is also on port 80, and conflicts. I thought I solved this by going to "Edit Bindings" and changing the "Default Web Site's" port to 81 and leaving my new site on 80. I still could not start my new site.
I had to delete and re-create my new web site, then I could start it.
It's like it still thought "Default Web Site" was on 80, even though it wasn't. Even an iisreset, a recycle of my new site's app pool and web site all did not work. Maybe if I had restarted the site/app pool of the "Default Web Site", maybe that would've worked, too, but didn't try it - just deleted/re-created my new site. But that was enough to break through the "Default Web Site" keeping a hold of that port!
I also received this error, but it was not because of multiple sites (my installation of IIS only had a single site with a single binding).
Running netstat -ano showed nothing listening on port 8624.
The problem was that a URL Reservation was generated previously for a different web server. I was able to query the URL ACLs with the following command in PowerShell as administrator:
netsh http show urlacl
To remove it, enter the following (replace the last argument with the reserved URL from the show urlacl query):
netsh http delete urlacl http://*:8624/
or more specifically, go to cmd and type in :
netstat -aon | find ":80"
Go to Cmd, then type netstat -a
Look for local address or local port for 80, or http
After reboot of a system the "Windows Sync Share" service was occupying port 80 and 443. This service needed to be stopped allowing the default website on 80 to start. Changing the "Windows Sync Share" service from "automatic" to "disabled" prevented this from reoccurring.
I had the same issue. In my case there was only one site. Somehow the install of a certificate created a second https binding?! Deleting one of the bindings solved the problem.
I had the same issue. Found that I had to bind my application in https mode, a cert is installed on my PC which defaults to 443 port when binding.
You have to set an Host name on the ftp sites, even fictitious.
Than you have to use this login name notation hostname|username

When I try to start a site in IIS it says:
the process can't access the file because it used by another process
I searched in Google and found that another site may have been using Port 80 but in MyIIS I see that only this site is using Port 80. What else could be using Port 80 or is there another issue involved?
Check using netstat -aon or netstat -aon | findstr 0.0:80 in a command prompt to see which Process Id is LISTENING to port :80 and then watch for that Process Id (PID) in Task Manager with view->select columns-> process id checked. End that process, restart IIS and you are done. (Note: if you have Skype installed, try exiting that process first.)
In a modern Task Manager, you need to go on the Details tab to search for the PID. Or, as mentioned by #Nikita G in the comments, you can use this command to find the task from your command prompt:
tasklist /FI "PID eq 123"
Note: change 123 with the PID returned from the first command.
It is happening because a different process is using port 80, it may be a chat application on your PC like Skype.
First, change the default web site port which was 80 to some unused port (e.g. 8087). To achieve this right click the application and then click on 'Edit Binding'.
After this port change restart again.
Now you can identify which process is blocking the IIS Port 80. To check this use netstat command which displays the details of port along with the process ID.
Sign out of Skype and try again. I have experienced the same issue and I just logged out of Skype and then reset my IIS. It worked for me.
You can also run this command to find out which application or service is using the port and then trace it down in Task manager (Provided it's not the Web Deploy Agent Service).
netstat -o -n -a | findstr 0.0:80
Then open Task manager, go to Processes, click the "Show processes for all users" checkbox and then click the View menu and Go to the Columns, add the PID column.
Match the Process ID from the netstat command to the PID in task manager and you will find the service or application that's using the port.
As others have said, something else may be using port 80 or 443. It was VMWare Workstation Server for me, but check other answers for how to use netstat.
I think this link gives a pretty good explanation and fix of this problem http://support.microsoft.com/KB/890015
Most of the time; it's caused by one of the two reasons:
1) port 80 is being used by something else and as suggested by others you can use netstat -o -n -a |findstr 0.0:80 to see whether this is the case. If yes then kill the process from task manager (tick show processes from all users)
2) if port 80 is not used, the second cause is potentially an invalid ip address in the ListenOnlyList filed in the registry key of HTTP->Parameters. If you follow the link to set the key manually or in fact you can use (xp and server 2003) httpcfg delete iplisten -i ipaddress to delete the invalid ip address.
You must restart the http once you edit the ipaddress!
In my case, it was the "Sync Share Service" (SyncShareSvc) that was running and using port 80.
netstat showed 80 as free, though. I could get the site to run on another port, but not 80. if I added a Host name, IIS would allow me to start the site, but I'd get prompted for Digest authentication when browsing to localhost (or any host name I added). Only Anonymous and Forms Auth were enabled in IIS...
I also found that, after stopping IIS, http://localhost still prompted me for Digest authentication.
The solution - in my case - was to remove File and Storage Services > Files and iSCSI Services >
"Work Folders" from the services installed (restart required).
After removing the "Work Folders" service and restarted, IIS worked as expected.
My case was after installing RD Web Access, the original default websites couldn't be started. Removed the RD Web Access role still same. Removed port 443 binding solved the issue.
Most times when this happens by web developers is the reason apache, so if you go to the config file from apache! open it up and search with ctrl + f to 80 and change the ip you will see to 8080 and the sentence beneath there with 80 to 8080 and you need to confige that in you xampp, or the program u are using currently
Hope I'll help u guys out
In order to get more meaningful information, one way is to also get ownership information when issuing netstat so that you know the process which is using either 80 (default http binding) or 443 (if https binding is defined):
netstat -ab
In my case the culprit was vmware:
TCP 0.0.0.0:443 ComputerName:0 LISTENING
[vmware-hostd.exe]
netstat can be piped into find to search for ports 80 or 443 (e.g. find ":443"), but these particular active connection will show at the beginning of the list at they are easy to see.
When I am trying to run Apache, it does not run. It tries to access the port 80 but port 80 is listening by a system process having PID 4.
How I can stop the "system" process?
Windows provides an excellent tool called Resource-Monitor (resmon.exe). On the network tab, it gives you a detailed view of what programs are listening on what ports on you computer. Just open that tool to find out the program currently listening on port-80 (whether its IIS or something else). Then all you have to do is end that process and remove it from your startup in case it is sitting there.
Port 80 is by default used by IIS. If you are running IIS on your machine, then you can stop it as explained here.
Skype also use port 80, so you may turn off skype and reload your apache server.
