due to hurricane sandy we had to move some servers to another site, one of them being an exchange server (2007). in doing so, we needed to change the IP of the server. this server also has 2 NIC cards that are multi honed using hp configuration utility
we moved the server back to the original site over the weekend and changed the IP back, but now in DNS we are seeing both addresses, both the temporary from when we moved the server, and the permanent for its original and final location
we delete the address that shouldnt be in DNS, but it keeps coming back and replicating throughout our entire domain.
any ideas why it keeps showing up?
one of my theories is that the person that changed the IP back, did so through network connections in windows server, and not through the HP configuration utility, and the hp config utility is updating the DNS record with the old address and the NICs are updating with the new address via windows... any thoughts?
