Hi
I have done follow below procedure
Step 1: If my primary DC goes down , First I will make sure to seize my FSMO roles to Additional domain controller ( I have done )
Step 2: Once all the roles seized , I will go ahead the configure time service on my new PDC Emulator holding DC ( i.e on addititonal domain controller where I have seized the roles). ( I have done )
Step 3: Once this is done I will run netdom query fsmo to make sure my ADC holds all the FSMO roles ( I have done )
Step 4: I will perform metadata cleanup of my primary DC which has got failed and also make sure that none of the old DC DNS entries exists in my domain (I have done )
Step 5: After accomplishing this , I will go ahead and rebuild my primary DC by installing server os in it and run dcpromo on it and wait for replication
Step 6: Once this is done I will transfer back all my FSMO roles from my ADC ( You need to configure time service once again if you are transffereing the roles
Please tell me, how rebuild My primary DC by installing server os in it and run dcpromo on it and wait for replication ?
Thanks so much !
