Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Is there anyway to see the DHCP options configured on the server from a windows client (win 7) with no login / admin access to the server?

I edited your question to ensure that it remained on topic for the site and appropriate for professional system administrators. I'd suggest leaving as it is. The question is exactly the same, just in a different context. –  Dan Sep 4 '13 at 16:02
    
@gordatron Dan is trying to keep your question on topic and open, and you keep rolling back his edits. As a result, I'm downvoting the question (very poor in its current form) and voting to close ("mainly because I am curious" would be off topic as not being in a professional capacity) –  Wesley Sep 4 '13 at 16:06
    
I chose that wording as I have other means of getting this information - asking the people who administer those servers for example. but I would like to know if there is away of doing this on a clients network so i can see where phones are booting from etc without bothering anyone. –  gordatron Sep 4 '13 at 16:10
    
I was up for removing that line but the other changes to me do not reflect the nature of my questions as i did not want to mislead people into thinking i was trouble shooting a dhcp problem. –  gordatron Sep 4 '13 at 16:12
    
I voted to close.. its not a professional way of doing it. just wanting to see some things immediately when really i should just wait for the right person. therefore it seems more of a superuser question if anything. –  gordatron Sep 4 '13 at 16:34

If you have local admin access to your workstation you can do this with Wireshark.. Of course you can just run ipconfig /all for the basic information but with Wireshark you will see all of the options the DHCP server is sending, not just the ones your client is using.

Thanks.. gonna hold on for a little to see if there is a non-packet sniffing option. using wireshark is not ideal in all circumstances. –  gordatron Sep 4 '13 at 15:44

You should be able to get information using the capture mode very well using Wireshark. Due to the nature of DHCP, it broadcast UDP packets to everyone in your local subnet (they do not pass through routers). It has to do this because it is meant to setup network configurations on clients which do not yet have an IP and don't yet know the subnet...etc. The packets are hitting your machine anyway and they're normally thrown away. No one will ever notice if you just inspect them. Sending your own false DHCP requests will get you into trouble very fast (found that out the hard way @ work myself). –  krowe Sep 4 '13 at 16:38
