(I am new to this Field)
we have Primary Domain Controller (PDC) with name DC1, and Domain Name DC.local, and one Additional Domain Controller (ADC) with name DC2.
DNS and DHCP are also in PDC and ADC.
from three years i face no problem as Whatever change i made in PDC it replicated to ADC.
But last week our ADC i.e. DC1 become down, and we are unable to Ping the Domain DC.local, and we are also unable to open the local Web based applications (if i put IP address instead of Machine Name, It is Working).
but users are able to login to Domain with no problems.
- We have DNS integreted with AD
- Any change in DNS in DC1 replicated to DNS in DC2
I am Confused that why ADC i.e. DC2 is not Fully Replacing the PDC i.e. DC1
