Hi!

I want to know by default sql server runs on port 1433.So, if the server has default and named instance , can it both run on port 1433?

Thanks.

No, each instance must have its own port.

Just to confirm what Luis said... no, you can't. The Port is how it communicates and knows what belongs to it, everything else is an alias.

Why would you want to do this, or even care?

In my opinion, setting the actual port number for each instance should be avoided unless absolutely necessary. Leave this to the SQL Server Browser Service
