NETBIOS is a Microsoft legacy naming convention that has a flat namespace of a maximum of 15 characters with a service identifier. Each computer name has three separate entries in its database, called WINS and it uses a flat file, called the LMHosts file.
The entry for PC1 as a WINS database would be:
- PC1 <00>: The <00> represents the workstation service
- PC2 <03>: The <03> represents the messenger service
- PC3 <20>: The <20> represents the server service
