First of all, the server network is normal, it may be that the firewall on the server has mistakenly blocked the internal IP of some computers, so turn off the firewall such as windows on the server and try again.

Judging from the situation you described, the so-called part of the server has its own network is normal, because some people can ping and remote! Then the problem may be with the switch or the hardware firewall. If you have a hardware firewall in your computer room, it is very likely that it is caused by him, just release all the shielded IPs on the firewall!

If you don't have a hardware firewall, reboot the upper-layer switch and try it.

Directly install the NetMan remote software on every computer, which is very convenient and powerful. The software is very good, I have used it for more than half a year, and it is easy to get started, first of all, I am not advertising, but I just recommend the software that I feel good to you.

Is the network card unstable The server generally has two network cards, you turn off one and turn on the other to see.

Hello. Let me answer your question.

The ping command is just a common command to check the response speed of a local connection server. But to be safe. Users can disable ping commands on the server through security policies.

At this time, the ping server does not get a response. There are also some high-hardware anti-DDoC data centers that will directly set a ping ban on the routerSo just because you ping doesn't mean you can do it remotely.

And the fact that the ping does not work does not replace the inability to remote. In general, there are several reasons why you may not be able to connect:

Remote connectivity is not enabled locally. It needs to be enabled in My Computer - Properties - Remote.

The server has a remote port. In remote cases, you need to put the port number after the IP address.

The logged-in user has exceeded the maximum number of connections. You'll need to wait for other users to log out before logging in.

The server needs to be connected remotely.

The corresponding firewall settings of the server.

Is it that the IP has a port number added? Or the server disables the 3389 remote port. If I have any questions about the Times Internet host I use, I can directly ask customer service.
