  • Fix an incorrect IP address on our DNS server

    We are running 2003 server and dns for the network. A website changed its iP address and we still have the old one cached. How can we fix this? Ipconfig /flushdns on the client and server did nothing nor did restarting the dns service on the client and server.

  • IP address question.

    I have some access units that come from the factory with the same default IP address. When we connect the units to the network to configure them we get IP address conflicts. Is there any way to isolate the units so we can configure them without having to do one at a time? Thanks, Ernesto
