  • DC. DNS and DHCP on the same Server

    I am deploying a new server (Dell PE2950) running DC and DNS (the domain is AD 2003 and I am using integrated DNS).

    Question 1: I have two nics on the server and was going to team them (fault tolerance etc). Are there any issues in doing this?

    Question 2: As the server I am using is powerful, I was contemplating using DHCP on the server. One nic for DC and DNS, the other nic for DHCP on a different VLAN. Any issues in doing this?

    Thanks in advance.

    1. No problem with teaming but make sure you have the most up to date drivers installed.

    2. You can't do both? Is there a reason for the separate VLAN? Will clients be connecting to AD etc Do you have some more info on the setup please?
    cheers

      We have two vlans, one is for servers and the other is for users.
      I was going to place the server in the server vlan using one nic (AD and DNS will run on this nic). I was thinking of using the second nic and putting that in the user vlan for DHCP.
      The alternative would be to team the nics, place the server in the user vlan and run all services (AD/DNS and DHCP).

        A) why teaming? This is not really a fault tolerance. I would keep it simple to use only one nic.
        more then enough unless you really have a high throughput on one nic.

        B) just place it into the server vlan. Use a IP helper on the switches to forward the dhcp/bootp requests.

          Many thanks for the pointer to IP Helpder. I just spoke to my network team and they can easily to this. Do you recommend not teaming the nics. We have two switches stacked in place. I was planning on teaming the nics and splitting them between the switches.

            Well, personally I think that Windows fails sooner then a switch or nic.
            However if it's feel better for you, go ahead. It's possible

            An iphelper address is very easy to configure. It cost them more time to logon and logoff then configure the iphelper address

              Thanks everyone for the feedback. I have decided to go with one nic and use the switches IP helper function.

              Thanks Dumber for pointing me at the IP helper.

                  Is Teaming NIC Cards necessary at all? I've heard people say that if you have two GB Nic's, and you team them you get 2.0gps rather than 1gps. And if 1 NIC fails it has the other to fall back on. I was always under the impression you use 1 NIC on 1 network and you can use the 2nd NIC on another network. is that correct?

                  To me, seeing 2 nic's teamed together to show 2.0gps wouldnt make sense because if the nic(s) are connected to a 1 GB switch, then how can the throughput be doubled? In a sense it looks like its double, but in reality the switch can only handle 1GB so your throughput would only be at 1GB .. am i making sense?

                    The ports on the switch are limited to 1 GB but the switch itself internaly can handle much more than 1 GB between ports.

                    I think its called blackplane speed?

                      The speed of a backplane is indeed very important for a switch.
                      How faster the backplane how faster the switch internally is.

                      With Teaming you can create one virtual 2GB nic. It's a long time I've seen it and most of time it gaves more problems then joy, at least, a couple of years ago.

                      Also, Most of the time 1Gb is more then enough.

                        Re: DC. DNS and DHCP on the same Server

                        Ok - but what about for fault tolerant? Is teaming up 2 nic cards like on an hp dl360 server used for fault tolerant? are there any docs out there that say that this is true or not? I never thought this was the case but I have heard that it is but now I'm not sure which is correct

                          It will work, dough I couldn't find any documents about it that fast.
