Windows Server 2012 R2 A interface é desconhecida após a renomeação

Renomeei o nome do computador do meu único DC no meu domínio de teste. No entanto, parece que o banco de dados não está completamente atualizado. Eu encontrei a tela azul 0xc00002e2 após a primeira reinicialização. Em seguida, tentei corrigi-lo usando os comandos ntdsutil -> Compact to para reconstruir o arquivo ntds.dit.

O servidor finalmente conseguiu inicializar normalmente. Mas, não posso usar nenhum serviço AD agora. Aqui está o que o dcdiag está dizendo:

Directory Server Diagnosis

   Trying to find home server...
   Home Server = dc1

Parece que o servidor estava tentando se conectar ao sdc.sea.nr, que é o nome que eu pretendia renomear. Mas atualmente o nome do computador ainda está mostrando o antigo e não consegui adicionar um registro A no servidor DNS local. Como devo corrigir isso?
