Quite often when I’m checking out a SharePoint Server I eventually want to get access to the SQL Server, that the SP Server is using for DB stuff. There is really no a lot of possibilites to do this. In SharePoin settings you will find references to the DB Servers alias (a friendly name), but not the actuall address or DNS resolvable name.
In order to find SharePoint Servers resolvable name you need to use the CLICONFIG tool.
You will usually find it here:
C:\Windows\System32\cliconfg.exe (64 bit version of cliconfig.exe)
After opening cliconfig and going to Alias tab, you will be able to identify your SQL Server name.
