SQL Server DB: where could I find the TCP port configured?

Example.

I don't have access to the SQL Server machine (so I cannot use SQL Server Management Studio and so on).
I cannot run netstat and so on (just an example).

Where could I read (on the SEP Manager machine) the TCP port used for DB communication (the one configured during the installation)?

I think there is a conf file inside wich this information is stored... or not?
Or a log that tell me "Open connection on xxxx server on yyyy port".

Thanks!
