As you all know, Microsoft loves trick scenario questions. Remember that all three of the following services must exist on the network in order for a RIS Server to operate:

1. DHCP Server: Needed for RIS clients to obtain their network configurations.

2. DNS Server: This is needed for RIS to resolve the IP addresses of client machines and directory servers.

3. Active Directory: RIS requires AD in order to locate existing client computers and RIS Servers on the network.

The above three services do not have to be installed on the RIS Server, but they must exist on the network. You're sure to see some variant of this one on the exam. Good luck!

Thank you for the advice. I just was reading about that to.

Thanks

they love to try and trick you with non BootP routers..make sure the DHCP server can service the appropriate subnets of the network when a router is involved....if not use DHCP Relay Agents...hope this helps

I agree with poudin...if you see one of these digrams and see a router labeled "Non HFC-1284 compliant router" (it's something like that...the actuall number might be wrong, but it's close) then that is a BIG RED FLAG that you need to look out for. That means that the question is probably going to say "Half of your client PC's can't connect to the RIS server...why can't they?" Becuase they can't get an address from the DHCP server that is off on another segment somewhere. If the router *was* HFC-1284 (again, that number might be wrong) compliant, it would be passing the DHCP traffic, and those PC's would be getting an address. The solution is to add a DHCP relay agent to let the PC's on the other subnet lease addresses.

Thanks for the tip.

That is the first I have heard of an DHCP Relay agent or an "Non HFC-1284 compliant router". It hasn't come up in any of the study material.

The only place that I ever saw it was in the Windows 2000 Pro Transcender. I think it's in the official Microsoft 70-210 study book as well...been a while since I read it, though.

A Boot-p compliant router is rfc 1542 compliant. Remember that as you could quite possibly most likely see it in the near future.

Thanks sablackspot...I knew it was something like that. Thanks for posting the right info. It's almost a guarantee that you'll see it on the test.

RFC stands for Request for Comment, and is the basis for all things TCP/IP.
As we all know, routers do not pass broadcast. However, the first packet sent by the DHCP client, known as the discover packet, is broadcast-based. A router that is rfc 1542 compliant will leave ports 67, 68 UDP open and allow broadcast packets to go through and reach the DHCP server. For more info, see my DHCP guide in the study guide section at www.mcsefreak.com
