Knowing Hostnames and Renaming Windows 8 Computer

What Is a Hostname?

In all post-Windows 98 computers, a hostname is the name of the computer that administrators specify either during the installation of the operating system, or after the installation has completed successfully.

Although Windows 98 computers also had computer names, they were called NetBIOS names instead of hostnames. NetBIOS names can only contain 15 characters, whereas hostnames can have up to 63 characters.

When a name is specified for a post-Windows 98 computer, the OS automatically assigns a NetBIOS name on the basis of the given hostname. NetBIOS name in such cases is the same as the hostname, provided the name is of 15 characters or less in length.

Advantages of Hostnames

As discussed above, Windows 98 used NetBIOS names which only had 15 characters. NetBIOS names were only recognized by WINS servers when name resolution was needed, and were not capable of communicating with the computers that belonged to any other network. On the other hand, hostnames are recognized by the DNS servers, hence enabling internetwork communication between the computers.

Requirement of Renaming a Computer

While working in organizations where there are several computers connected to each other, administrators may sometimes want to rename a computer in case the naming convention policy is modified, or the computer is decided to be used for a different purpose.

Administrators may also want to rename the computer to avoid naming conflicts, in case any other computer has been assigned with the same hostname.

Limitations and Considerations While Renaming a Computer

  • A computer can be renamed only by the administrator of the computer.
  • If a computer is a member of an Active Directory domain, it should be removed from the domain before it is renamed.
  • Although Windows prompts administrators to restart the computer after renaming, in case it doesn’t, it should be restarted manually before making any further modifications.
  • In most cases renaming a computer does not affect the policies that have been applied on it.
  • To restrict or limit communication of a computer with other computers in the network while renaming, the IP address of the computer should also be modified accordingly.
