How to verify connectivity using PowerShell

0 users found this article helpful

Information

As part of troubleshooting, it is required to check if a port on a remote server is open and the connection is possible. This can be done by using Windows Powershell cmdlet called  Test-NetworkConnection

1. Run Windows Powershell.

2. type the following command:

tnc <Server> - port <PortNumber>

3. You need to check the value of TcpTestSucceeded. It gives True if the port is open and false if the port is closed.

 

Example

We can verify if connectivity to Parallels server is possible using this command:

tnc ras.parallels.com -port 443

Note: In some of the cases you may notice that PingSucceeded=False  while TcpTestSucceeded=True. This is normal behavior when ICMP Ping is prohibited.
