>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?

If you have PowerShell available, you can test networks connections.
At the program prompt, enter
powershell (or search for it), and at the powershell prompt, issue a Test-NetConnection command in the form
Test-NetConnection -ComputerName www.levelextreme.com -Port 80
(exchange the computer name and port for the ones you want to test). Something like this will be returned (but not with parts in Portuguese, I'll presume):
ComputerName : www.levelextreme.com
RemoteAddress : 64.18.88.26
RemotePort : 80
InterfaceAlias : Ligação de rede sem fios
SourceAddress : 192.168.1.71
TcpTestSucceeded : True
