Rouge Machine Conflicts with Server IP 1

[PU36]

This morning our main DHCP server failed. While it failed the computers that booted were geting IP Address from a rouge server (have since found it and burned it). However there are some computers that aquired those bad IP addresses. Is there a way to determine what the computers names are that have the rouge IP address? I know the IP of the machines, but not their name.

The addresses are currently conflicting with numerous servers and walking to 500 machines isn't an option.

I have tried the following;

1. nbtstat -A <IP Address> which returned nothing
2. \\<IP Address>\C$ (I have Domain Admin rights)

Any ideas or tools in mind?

Thanks

Try downloading LANSPY (or an equivalent IP scan tool) and have it run through the SUBNET that these machines are on.
