Answer 1

SQL Server 2000 Programs | MS SQL Server | Client Network Utility | Select TCP_IP then Properties

SQL Server 2005 Programs | SQL Server | SQL Server Configuration Manager | Select Protocols for MSSQLSERVER or select Client Protocols and right click on TCP/IP

Answer 2

In our enterprise I don't have access to MSSQL Server, so I can'r access the system tables.

What works for me is:

1. capture the network traffic Wireshark (run as Administrator, select Network Interface),while opening connection to server.
2. Find the ip address with ping
3. filter with ip.dst == x.x.x.x

The port is shown in the column info in the format src.port -> dst.port

Answer 4

Perhaps not the best options but just another way is to read the Windows Registry in the host machine, on elevated PowerShell prompt you can do something like this:

#Get SQL instance's Port number using Windows Registry:
$instName = (Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server').InstalledInstances[0]
$tcpPort = (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\$instName\MSSQLServer\SuperSocketNetLib\Tcp").TcpPort
Write-Host The SQL Instance:  `"$instName`"  is listening on `"$tcpPort`"  "TcpPort."

Ensure to run this PowerShell script in the Host Server (that hosts your SQL instance / SQL Server installation), which means you have to first RDP into the SQL Server/Box/VM, then run this code.

DECLARE       @portNumber   NVARCHAR(10)
EXEC   xp_instance_regread
@rootkey    = 'HKEY_LOCAL_MACHINE',
@key        =
'Software\Microsoft\Microsoft SQL Server\MSSQLServer\SuperSocketNetLib\Tcp\IpAll',
@value_name = 'TcpDynamicPorts',
@value      = @portNumber OUTPUT
SELECT [Port Number] = @portNumber
GO
