WSName, or Workstation Name Changer, is a freeware utility that automates the process of computer renaming. It was created by former Novell desktop management consultant David Clarke, who continues to update it periodically. WSName is a 32-bit application supported by Windows 9x, Windows NT4, Windows 2000, Windows XP, Windows Server 2003, Windows Vista and Windows 7.
In Windows 2000 and later, the utility, also known as wsname.exe, offers the ability to re-set both the hostname and the NetBIOS names of either a stand-alone workstation or one within a domain using the SetComputerNameEx API. Local administrator permissions are required, and each computer will need to be rebooted in order for the name change to be completed.
WSName supports many command-line functions that enable additional features, such as renaming remote computers via Windows Management Instrumentation, and support for reverse DNS lookup.
