What does a netsh int IP reset do?

What happens if I reset my TCP IP?

This page explains how you can reset your IP configuration to something that will cause your server to work.

This is called hard reset and, depending on the settings of the interface, the procedure works either by changing the state of the hardware (for example: setting a field in the MAC frame to "invalid") or by forcing the hardware into the default state.

The most common case of a hard reset is for an ISDN line when it's idle. In this case, resetting the TCP/IP will force the link layer to change the frame format so the phone is told to send a new line request frame rather than sending a busy tone. This is the default procedure used by all ISDN lines so the only way to break the ISDN connection without first resetting the IP configuration is to cut the line.)

How does a Linux PC work? From one point of view, Linux is a computer with a kernel in which several programs run and interact. All programs use the kernel in various ways - there's no magic trick to the fact that it's often more convenient to talk to a program directly than via a virtual file system, database, web server, or whatever. But some systems, such as those running the TCP/IP stack, require higher-level cooperation from the programs running in the kernel. It is these systems that the kernel has responsibility for keeping in good working order.

It's not all bad - you may have a machine that won't boot unless you reset its TCP/IP configuration every once in a while. But on the whole, the Linux kernel knows when TCP/IP needs to be reset and makes sure that happens - there's no chance a program could forget to do this or that program could go haywire.

After reset, the network interfaces and other hardware will revert to their previous state. The IP address and associated routing table information will be lost. You will have to configure the same IP addresses again and again. You may be able to ping something just once and get an ICMP-return, but that can't be relied upon. Also, once you've reset your IP, you'll have to run the same commands again.

Is it safe to do netsh Winsock reset?

How often does this happens? I know that the user has to input a login password, but what if someone gains remote access (physical) and logs into my computer without inputting a login password. Will that work? My only worry is that I don't want anyone to know that I'm trying to change a setting for a server if it's connected to the internet as I have a bunch of documents on there. Also I don't want to cause someone else physical harm, I don't want to mess anything up, but in this situation would that do any damage? Edit: Windows version 8. Yes it's safe to do so but you shouldn't run this command from an untrusted user. If anyone could access to your system remotely they may be able to see or even control your computer.

How to reset TCP IP using netsh?

In one of the questions I have been asked here in one of the posts, its regarding how to reset TCP and UDP connections in Windows command prompt or cmd.

NET.

Here is what is in the title : In C# code using the Console.WriteLine can I test if a UDP port is reachable or not. If not, how can I tell it the host is trying to open the port.

As per my requirement this question is not relevant but I am curious to know if we can use the following code to simulate such condition and make a connection? If someone explains it in a detail will be highly appreciated.I have tried searching the NETs but not got the required information Thanks. Edit. I came across a different problem which might help some of the people reading this post. Its because, my requirement was that the IP should be different everytime for an attempt of making a connection and I dont know the logic of how this is supposed to happen. So this question is also invalid now. If I try to make a connection then in CMD/Cmd NET and windows as well it gives this response. "Windows could not find xxxx.0. This may cause you to miss some incoming data. This may affect the ability of other programs to communicate with each other. To prevent this, stop or restart the computer."

I dont want that message. And yes I have checked these commands as per this example: netsh firewall porttypes add v 4190. This will add port number 4190 as an allowed port for traffic on the inet type. But I am unable to find if any method to allow the connection.And this only creates new port. And then if my device(client) is not even allowing to send its response.I want something which would be able to simulate any connection from my computer to the ip address of the device.

The error Windows could not find xxx. Appears when the service, firewall, or router cannot be reached over a network address translation (NAT) gateway to connect to the server.

The following steps can be taken:
