    DNS

    Hi,

    We changed the ip of the dns servers over the holidays and changed the settings in the DHCP server Scope. But for some reason so pc's are still picking up the old ip.

    Is there a way to flush the DNS settings over domain level?

    Cheers Steve

    If the computers are all completely powered off and restarted it should grab new DHCP information. If all of your DHCP servers are configured properly it should pick this up. You could also look at deleting all of the active dynamic dhcp reservations in the DHCP managment console before the mass shutdown and restart which will force a reregistration with the server rather than just a renewal.

    Also check the TCP/IP properties on the machines. It's possible to have the IP assigned by DHCP and over ride the DNS settings locally.

    Hi

    Whats happening is we used to have an old DNS server and it has been redundant for some time. I noticed the oter day clients started getting the dns of that server. So i logged onto the server and in the "configure your server wizard" it was still listed as a DNS server. So i uninstalled it as a DNS server and its still doesn't make a difference.

    How is the clients picking up the DNS address from this server? is it in the error logs its says that this server is now the master browser?

    HELP!!


    Cheers

    When you do an "ipconfig /all" on one of the effected computers is the DHCP server IP the one that you expect it to be?

    You can also trial "ipconfig /release" then "ipconfig /renew" on an affected system and se if that fixes it on that individual machine.

    I do hope it isn't set in group policy as this can get especially messy.
