I have a Microsoft SQL Server database on a Windows VM currently serving data over over `server.fq.d.n,<port-number>`. Users are able to connect to this database just fine using this `<fqdn>,<port>` address, but some of them want to connect with an alias that is just an fqdn **without** a port number `alias.fq.d.n`. 

How would I go about doing this? 

My database instance is named `xyz-services\foo`.
