>>Hi,

>>I need to check if a client computer has port 1433 open. This client (unlike other client PCs) has a problem connecting to the SQL Server. When I Google for "how to find if port 1433 is open" I come across messages pointing to the TELNET command. I tried telnet on my computer (in Command prompt) but get the message that this command "is not recognized ...". Is there another command that will quickly tell me (on that client PC) if port 1433 is open or not?

First, thank you. It appears that I have Powershell on my computer. Tomorrow I will get a connection to the customer computer to test. But here is what I don't understand. If I want to test connection to the SQL server (customer SQL server) how would I change the Test-netconnection? Say, I change the "computername" with the VM computer name where SQL is installed. But where would I indicate the SQL server name? Because I am trying to determine if the PC has connection to the SQL Server.
