One of our server has only a named instance—no default instance. However, users are able to connect the default instance. Under the hood, users are in fact connecting to the named instance.

My conclusion: somewhere there is a name resolution happening. Some process, converts SERVERNAME TO SERVERNAME\INSTANCE_NAME.

There are no entries in sys.servers for this mapping. Also, there are no ALIAS entries in the network configuration utility.

Has anyone seen this behavior?

But is there an alias on the client machines? Or is the named instance using the default port?

There is No alias on the client machine. I am doing this on the server itself, by loging remotely. I am pretty sure that the server is using the default port? Would, using the default port, cause this behavior?

Yes, all that named instances are are SQL services listening on non-default ports.

Now a named instance would not be listening on the default port (1433) by default, someone would have to have set that up
