In the company I work for they have a Mikrotik RB850G. Now, for some reason the mikrotik has a DHCP server live on it, and so does our domain controller.
Anybody knows that having 2 dhcp servers is not good.
Here’s the thing.
- Both DHCP servers are in different subnets
- Both DHCP servers have their own gateway (mikrotik seems to have a gateway IP on it for each of the 2 scopes to access)
- Some of the computers are only showing up on router DHCP and no on domain controller dhcp
- Some of the computers are only showing up on the domain controller DHCP and not the router dhcp
- Some of the computers are showing up on both router and domain controller DHCP but the computer is only picking up 1 of the IP addresses
- In the office we have 2 ports near each of the desks. The left will give out an IP address from router range, and right port will give out IP address from the domain controller range… so my question is how are some getting 2 IP’s and also, how do you setup a wall port to only pick up a specific DHCP server?
Now, I know barely anything about mikrotik’s and i’m using winbox to access it, what i’d like to do is to switch everything to just use the DHCP on the server, and what you may say is “just turn off the domain controller dhcp”. Problem is that the domain controller is on that range that it’s handing out. So what would I need to do to ensure that I could turn off the domain controller dhcp safely so that everything would just look at the router dhcp? Because the problem I have is that i’ve tried taking one of the computers that is only on the domain controller’s dhcp range, and then staticly setting it to everything so that it’s on the routers DHCP range and it just does not want to work. So there must be something in the mikrotik’s settings that is telling certain ports on the switch that they can only receive a certain IP scope…if thats the case…how?
