Hello folks, this question means a lot me. The diagram of our organization is shown below. Now we are connected to
> Net Gear Switch<
> Windows Server 2008 R2
\> 30 Users
Now, the managers ( operational) have asked us a logical question when our network was down ( due to address conflict ) Where is our DHCP server ? Now , i guess the Linksys WRTG54 Wireless / Hub router is the DHCP server. But my question is : How will that device know, that it needs to act as the DHCP server , and it is the only DHCP server in our network? I do not know what you call that device , the frienldly Verizon Technician comes and installs . What is that "thing"?
This is frustrating.... i am a future network engineer, I am so.... @#$%@#$@#$34 at myself , that i want to know what it is its function? etc. is this the DHCP server?????? So how will the Linksys router know that it is the DHCP server?????? Will this thing give some sort of signal from it WAN port saying..."Hey whosoever is connected to me , you are the DHCP server" ? Or the DHCP server is somewhere beyond this LAN,,,,,What about the DNS where is this located??????
I might not be asking a technical question as such? But i am trying to learn how this DHCP works in the real world. I DO NOT NEED A PERFECT ANSWER, BUT IF I COULD GET A BRIEF OVERVIEW. I WOULD BE HAPPY!!!!!!
And we configured the Windows Sever 2008 R2 with Static IP and disable DHCP on it. So there is no chance that , it the DHCP. So tell me in terms of Home users also. How does this device know?????? Is this Wireless Router / Unmanaged Switch(Hub) the PATing device. Please guys , i could really use your help???????

Use wireshark to figure out what's going on!! Just joking. What I would advise is 1st disable all dhcp services on all of your devices. 2nd enable it only on one device. I will not steal someone's credit however here's the wiki answer to your question
or just google what is a dhcp server. Last, as a network engineer you should never panic if $*it hits the fan you must compose yourself!! If end uses including managers witness you panic. Kiss your responsibilities as a network engineer good bye alone with a little of your confidence and swagger. IT is a cut throat industry welcome to the arena.
