Arp ?a will give you: ??all the current arp entries by interrogating the current protocol data?? That would list you the IP and the MAC in the arp table for the current computer? Regards, Eduardo Herrmann de Freitas -----Mensagem original----- De: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000-bounce@xxxxxxxxxxxxx] Em nome de CSchwab@xxxxxxxx Enviada em: quarta-feira, 10 de setembro de 2003 16:40 Para: windows2000@xxxxxxxxxxxxx Assunto: [windows2000] MAC address to Computer Name. I received a duplicate TCPIP address on a windows 2000 server. Does anyone know of software or a command that will allow me to enter the "MAC" number and return the computer name? It would save me search each system for the MAC address. Thanks for any help. Clinton A Schwab Network Administrator CPAC, Inc.
