Where I work the IP wizzard decided to use static IP's for all the computers in 3 buildings. The problem is... he never kept track of the free IP's left. Is there a command that I can use to find out which IP's are used or still free? If so how do I do the task?

Have you tried these utilities?

Or you could assign static IPs to the servers and implement DHCP for the clients.

you cound just run something like active port scan do whole range of you network
you shound be able to tell by computername if you know them
How many pc ?
I wound suggest doing what AkaJohnDoe say and fire the guy who setup that way :> dhcp server is way easy to mange ip
you cound even do mac address resavtion for spefic macine pretty etc
But all server shound have static work station dynamic
I hope this was.nt you it guy setup that way what a magment night mare rember all ips figure out winch one is assigned to what not to mention the time it took to enter them all each machine
Is this windows server based network? dhcp server is part 2000 server family and it easy to setup -

I usually recommend a separate IP address scheme for internal (intranet) from external (extranet). That is, say my company's WWW.???.COM points to IP address 123.123.123.123, the internal network would be WWW.???.NET, have no external connections (other than perhaps some special VPN access paths), have another IP address scheme, unregistered on the outside world (although the domain WWW.???.NET would be registered, for protection), or perhaps registered elsewhere, who cares as it is internal only.
The servers would have static IP addresses in this internal, protected IP address range. The clients would have dynamic IP addresses (DHCP), also in this internal, protected IP address range. -

Or use a program like PortScanner by http://www.networkactiv.com/ It will do the job for all that are connected.

you've gotta be kidding.
this type of LAN rollout is the EXACT reason DCHP was invented.
like above poster said, fire the guy who set the LAN up like that.

Depending on the subnets, domains, network card setups, and protocols in use, you might be able to see the local neighborhood in Windows or even via a NET VIEW command in a command prompt (DOS) box.

Just wanted people to know that DHCP can't be used in all situations. -

True enough, but not keeping track of the IP addresses assigned would seem to be contrary to the concept of a secure LAN.
