I have a few machines that when I ping them they ping back with the wrong IP address. I have done an ipconfig /flushdns on them, but still they will not ping with the right address. I have checked the IP address on the DHCP server and it is correct with what is on the machine.
We were a small company with our own domain we got bought out by a bigger company with its own domain. For this example I will use Domain A for our old small domain and Domain B for the company that bought us out domain.
So right now all our computers are on Domain B. All the network configuration (DHCP, Gateway, Domain, and DNS) all come from Domain A. The only network configurations we have from Domain B is a few DNS suffixes that get pushed down via Group Policy. When I look in the Forward Lookup Zone on Domain A under Domain A’s domain I don’t see any of our computers that are on Domain B even though I’m pushing down DNS setting from Domain A. I do see in the Reverse Lookup Zone all the computers on Domain B and they all seem to have a PTR record.
The only reason we have Domain A is because the bigger company will not let us move our servers over to Domain B.
I guess my questions is could the problem that we are seeing be caused by us not pushing down network configurations for Domain B? If we configured our Domain and DNS to reflect Domain B instead of Domain A would that fix the problem with DNS that we are seeing?
We don’t have any admin access to Domain B.
