Yes, it's normal.
"Server" here doesn't mean that the computer as a whole is meant to be used as a server. Rather, it means that it acts as a server – it lets others connect to it – for some purpose or another. For example, when you set up file sharing on Windows, when someone from another computer browses your files, a program on your computer is accepting the connection and therefore acting as the server for the SMB file-sharing protocol.
And net config server
is specifically talking about the Windows component that acts as the file sharing server, which is installed by default on all Windows systems, internally called "LanmanServer".
Similarly, net config wksta
talks about the client side (which connects to file shares on other computers), and net config browser
is the component that discovers other computers on the network (used to be called "Network Neighbourhood").
(In fact, the whole net
command was originally introduced with LAN Manager, which added the same file sharing functionality to MS-DOS. Only Windows NT made the service management – net start
and net stop
– a bit more generic, but all other subcommands still deal with the Windows file sharing.)
