MR behind MX

[Abechara]

i have MR behind an MX, configured DHCP. 

when i change the DNS of MX for the DHCP to meet my requirement the MR has DNS error, 

the other users connected to MX hqs no issue, only happened on MR

the MR connected to MX same vlan with users

What changes do you make and is the MR on a static or dynamic IP?

[Abechara]

mr is configured as DHCP , when the dns in dhcp server in mx is changed to internal dns it gives error

After changing the MX to Internal DNS have you tried rebooting the MR to see if it acquires an IP address from the new DHCP server and clears the error?
