Is it using DHCP?

We are in the process of switching our LAN from static addressing to DHCP.
While in the switchover, it's pretty difficult to know who's using DHCP and
who's static other than visits to the console to check DHCP entries, which
has to be done manually and is time consuming for a whole LAN.

Anyone know of a way to remotely scan a LAN, and get information back as to
whether the hosts use static of dhcp addressing. IPCONFIG /ALL obviously
shows whether the interface is DHCP enabled or not. How can I remotely check
this??

Thanks

You don't say what your dhcp server is but likely most if not all provide
visibility into assigned dhcp addresses. My router for example assigns dhcp
addresses and I can in the router access a table of assigned addresses to
MAC. Static addresses do not show up in this table. So search the
documentation for your dhcp server to find whether or not it provides this
visibility.
 
There are several ways you can do this.

On the DHCP SERVER:

1. Open Control panel, administrative tools, then the DHCP
applet. Click on your server name, then scope, then
address leases. This will list all the computers that
currently have a DHCP lease. This is the simpliest way to
do it.

2. Run a script that will enumerate the IP settings for
computers in your domain. It will be able to tell you
weather the pc is dhcp enabled or not.
