Port will listen while other side ready application for work with port. Domain Controller Migration Windows Server 2008 R2 to Server 2012 - Duration: 15:59. BTNHD 108,570 views. My name is Steven Graves and I am a Senior Support Escalation Engineer on the Windows Core Team. In this blog, I will discuss how to configure MSDTC to use a specific port on Windows Server 2012/2012R2 as this has slightly changed from the way it is configured in Windows Server 2008 R2 in order to prevent overlapping ports. Why i can't telnet a particular port even if the port(tcp) is open By jobs4vjlx16 12 years ago I'm having a problem connecting to some clients running WinXP via a particular port(tcp). Welcome to Reddit, Literally out the box and have enabled RDP for remote admin yet rdp doesn't work and 'netstat -an' shows it isn't listening on 3389. Tried with the firewall off, no difference which figures since it would still need the service to be listening on 3389. Scouring the web shows a few people with similar issues but no obvious resolution. If it doesn't listen when you try changing it to another port I'd say that something is up with the application. (If you do change it to another port, you need to change the 'CommandCenterURL' parameter in the 'web.config' file in the ControlPanel folder the new port, too.

You can use the NETSTAT command to quickly see all the used and listening ports on your computer. Note it is not a complete substitute for a port scanning tool. If you'd like to have your computer remotely scanned for vulnerable open ports use our Security Scan instead.
To see a list of listening ports, open Command Prompt and type:
C:>netstat -ano |find /i 'listening'
You can change 'listening' to 'established' to see what ports your computer actually communicates on at the moment.
It is very useful to also use the -o switch with the netstat command to get a list of all the owning process ID associated with each connection. You can then use those process ids (PIDs) to find out the name of the processes associated with open/listening ports in the Windows Task Manager (the 'Details' tab lists process ids).
C:>netstat -ao |find /i 'listening'
To see all open, closing, established and listening ports, simply use:
C:>netstat -a (or netstat -ao in XP/Win2k3)
You can also make the netstat command refresh periodically by adding a number of seconds at the end, for example, to make it refresh every 5 seconds, use something like:
C:>netstat -an 5
Notes:
The netstat command has a number of other useful command line parameters, you can see short description of all of them using: netstat /?
You can see process identifiers using the following command at the command prompt: tasklist and tasklist /svc
Newer Windows versions can also get a list of ports through the Windows PowerShell, using the Get-NetTCPConnection command.
It is also a good idea to perform an outside security port scan to see what ports are open to the Internet. See: SG Security Scan

rate: avg: Thank you for this. However I have another problem. I have 6 computers daisy chained together to create a render farm. Two of my computers 'cannot connect to server, because target machine actively refused connection.' How can I get my main computer and the other 5 to 'speak' to eachother? Would my computer and the other 5 be listening on the same port? Also, on the main computer and the other 5, the same TCP ports are listening. Thank you, 'Actively refused connection' sounds like either a closed port, or firewall issue. You'd also have to make sure the necessary services are running on both computers to be able to establish the connection. I am not familiar with your OS/setup to offer more specific info. Hello, could you most kindly help me with port unavailable problem I have been having since I moved to Rogers (my new ISP). I have configured port forwarding in my gateway (Cisco DPC3825), and made exceptions in windows firewall for port 13000, but all the existing programs for open port checking say that it is not available. Today, I have found a cisco tools (https://supportforums.cisco.com/docs/DOC-10272), and followed its instructions, which showed that the port status is stealth, which according to Cisco is evidence for the ISP is blocking the port. So, I talked to the technical service of my ISP, and the supervisor assured me that port 13000 is not blocked either for TCP or UDP. And yet, this port is still not available for the particular program (freephoneline.ca) I am using it for. I have just followed your advice above to use netstat -a, but it does not list port 13000. Perhaps I have not done things right in my windows firewall, but at this point, I have no idea how to go about it. If you like I could send you all the test results I have made so far. I would very much like to have port 13000 working. Could you kindly help me with this? how to ports is open or not A port in 'stealth' mode simply means it is not responding, i.e. it does not report back that it is closed/open. It is the normal state for most ports behind a NAT router. It does not necessarily mean that your ISP is blocking it. I'd suggest trying to open another port, and check whether it is open with our security scan. If it remains in the same 'stealth' state, there is an issue with your port forwarding locally, rather than your ISP. Please also note you may be able to get answers much quicker on our forums, rather than the comments section. And what now? I've listed all the ports, but when I try to poke any of them with anycv 'open port checker' they are all closed. What's the catch? Where are the ports located actually ???u have different ports for different protocols like http SMTP .I really wanna know it can anyone help meh wid tat?? |

Other computers are having trouble even finding the running Postgresql 9.1 on my Windows 7 machine. Local connections work just fine of course.
In my pg_hba.conf I have:
In postgresql.conf I have (Yes, port 5433 is intentional):
Upon running
netstat -a -b
in the cmd I find:Heck, I even made a firewall exception:
The typical response from pgAdmin is always the dreaded:
Any ideas?

Here are the steps of troubleshooting I would recommend:
- From the local machine try the following. If they work you know the issue is not PostgreSQL. If they don't work then you know your issue is local to the machine.
- psql -h localhost -p 5433
- psql -h [external ip] -p 5433
- If the latter fails, try temporarily disabling all firewalls and trying again
- Now if that works the next step is to troubleshoot the network. Traceroute may be helpful here. Also try connecting to any other open ports using other software and make sure that works. From there, you may be able to figure out exactly where the packets are being dropped.

Make sure PostgreSQL Server is allowed through the firewall:
On the server machine, go to
Windows Server 2016 Port Not Listening
Control Panel > System and Security > Windows Firewall > Allow an app through Windows Firewall
Scroll through Allowed apps and features, make sure 'PostgreSQL Server' is checked.

I faced the same problem, it was resolved by turning off my Win Firewall and Antivirus
They were blocking the DB server connection

Add rule in firewall for postgres
Go to 'Control Pannel' =>> 'Windows Defender Firewall'
Then Choose 'Advanced Settings'(Mostly in Left Hand Side Vertical Options)This will open 'Windows Defender Firewall with Advanced Security On Local Computer'
Then Select 'Inbound Rule'.
Then Click On 'New Rule'. This will open 'New Inbound Rule Wizard'.
Select 'Program' and Click On Next.
Add Program Path of psql.exe. In my case psql.exe is at localtion 'C:Program FilesPostgreSQL9.6binpsql.exe'.
Select 'Allow the location'.
Check all checkbox for whom you want to apply the rule.
Give proper name and description for the rule. Then click on finish.
This will add new rule to access psql with localhost. Then try to run pgAdmin or access db with cmd.
