A computer that provides a workstation role, such as a computer that is running Microsoft Windows 2000 Professional or Microsoft Windows XP Professional, may become the master browser for the Computer Browser service. This behavior may not be what you want if you want a computer that is a member server to be the master browser.
This behavior occurs because workstation computers and member servers have an equal chance to become the master browser during the browser election process. The browser election process determines the master browser for the network segment.
