Ocorreu um erro durante a sincronização de NTP no Windows Server 2008 R2

Question

Eu tenho dois servidores Windows Server 2008 R2 Standard. O primeiro pode sincronizar corretamente seu tempo com o servidor NTP padrão time.windows.com , mas o segundo não pode.

O erro exibido é:

An error occurred while Windows was synchronizing with time.windows.com

Eu instalei o Wireshark em ambos e tentei uma sincronização NTP. No servidor de trabalho, posso ver a solicitação NTP e a resposta NTP. No entanto, no segundo servidor, não há solicitação de NTP (o Wireshark não vê nada).

O filtro que eu apliquei no Wireshark é simplesmente "ntp".

Eu tentei reiniciar o serviço Tempo do Windows e desativei o firewall, mas o problema ainda persiste. Como posso consertar isso?

    

Answer 1

Você gostaria de pegar alook para isso:

Eu get "Ocorreu um erro enquanto o Windows estava sincronizando com [nome do servidor de horário]." ao tentar sincronizar automaticamente o horário do PC

You can add a new rule to SPF following the steps delineated here. The application is w32Time located under System32 is memory serves right.

However if SPF doesn't complain, the problem is certainly elsewhere. I see to remember having had problems with time sync before. I really can't remember what the reason was in end. But two things seem to nag me:

The service was stopped or in Manual or something, and needed to be in Automatic(?). My router was blocking it Errors coming from the time servers alone seem unlikely. As you say you have tried others. But in any case KB262680 contains huge lists of time servers you can use.

Meanhile KB314054 reveals manual configuration instructions of the service in the registry along with a detailed explanation of all keys further down the page. Could be a case of a bad registry configuration.

All the best.
