Friends, just now realized something. We can not install the DNS Server Role in Windows Server 2008 R2 enables it not as a domain controller? I tried to enable the DNS Server Role, but I got a message that is obligatory to use the dcpromo and I'm not mistaken have enabled other times in the past. Can anyone clarify? Thank you! Ivanildo Teixeira Galvão

Hi I think you enable the role for Active directory but didnt run DCpromo, So can you try first if you are not useing it as a dc to remove the role and after install DNS role Best regards, Mark

Got it, just putting the AD DS role, I'll do this test and then post here. ThanksIvanildo Teixeira Galvão
