Browmon.exe - Browser Monitor
Browser Monitor is a tool with a GUI that monitors the status of browsers on selected domains. Browsers are shown on a per-domain and per-transport basis. The Windows Browser service maintains a list of all available domains and servers. Microsoft® Windows® 2000 Server and Microsoft® Windows® 2000 Professional continue to support the browser service, originally introduced with Microsoft® Windows® for Workgroups version 3.1, to provide for interoperability with domains and computers that are not Active Directory™–enabled.
