Para resolver isso, acabei restaurando a pasta sysvol de um backup. Não tenho certeza se essa foi a melhor maneira de corrigir isso, mas funcionou.
Parece que estou tendo vários problemas com nosso SBS. Eu acredito que este era originalmente domínio estava anteriormente em uma caixa do SBS 2003 antes de ser movido para esta caixa do SBS 2011 no ano passado, ele foi executado bem até ontem. Eu não posso ver nada que tenha mudado então.
Tudo parece apontar para o DNS, embora eu esteja lutando para identificar a causa real. O mais preocupante é quando tento abrir algo no SBS, como sites e serviços do AD.
