lookin for the right tools to solve a network problem server 2016

Copper Contributor

Hi,
I'm pretty noob with servers, so I'm looking for some general pointers.

The issue is that: a server runs a service on some none default port, something like 4567 or similar.
when i telnet localhost:4567 it answers so the service runs.

but when you try to connect from another server, it looks closed.

It's not a firewall issue, at least not external one.

so, my question is, what build in tools i have with server 2016 to start looking at the problem?

should i use a sniffer? which one? are there any logs for tcp connections with windows itself? ? maybe 3rd party software?

i will love to hear some idea's regarding how to approach the matter.

Try turning off the windows firewall.  This will tell you if it is the firewall that is blocking the connection.  Also, you need to make sure you can remote to the server directly.  Check to make sure you can ping the other server when you are logged into the problem server.

 

let me know how it goes.@kilonova
