I have a server hardware with installed windows server and DHCP server running on it.
My network is 192.168.0.0/24. A small issue we just faced is the client machines could not get an IP address from the dhcp server. I then checked that the server nic with the IP 192.168.0.250 which runs the dhcp server also had one more IP address in the 190/8 range. This was probably assigned for some testing purposes.
Once I removed the 190 IP the problem seemed to have been resolved. Microsoft's dhcp troubleshooting document mentions this in the first scenario but says nothing about multiple IPs on the same NIC.
I just needed to confirm if that was the issue or something else is happening under the hood. I have this query also because on this same network I had some issues like random machines not pinging their default gateway but could very well ping and access the rest of the network.
One more doubt i have is that will those multiple links going to the storage in anyway cause network loops. I don't have the idea about their configuration as of now.
