Laptops in 2000 Windows domain get ip addresses from rogue DHCP servers
Posted on 2007-11-15
I'm a relatively inexperienced system administrator, please help me understand the following problem.
In our Windows 2000 domain, laptops, which are members of the domain began acquiring IP addresses from a DHCP server that is not authorized in Active Directory.
In one of our departments, someone installed VMWare, with it came a DHCP service.
Today, all of a sudden, some of our laptop computers acquired ip addresses from that service instead of our own Windows DHCP server, I've verified that ours was the only one authorized.
How is that possible? How can I prevent that? Is there a way to find the "physical" source of this kind of problems? (I spent hours searching for the source of the problem today)
