Eu tenho um problema se manifestando em nossa rede que o principal emulador de PDC DC não é capaz de ter um bom tempo. É quase 80 segundos praticamente o tempo todo e eu não sei como corrigir isso.
A máquina é agora virtual (embora eu possa fazer dela uma pequena caixa física). a configuração do tempo w32 é:
PS c:\> w32tm /query /configuration

O status é ok:

O problema é que nunca está em sincronia:

Isso mostra um atraso consistente de 81-82 segundos. E uma sincronização não muda isso.
Alguém tem uma ideia do motivo?
A pedido, aqui um estado mais detalhado:

E mais alguma saída que alguém pediu:

Essas são as três máquinas atualmente na rede. Note que aquele com ckg no nome é cerca de 170ms de distância através de uma VPN - a diferença da Europa Central para Chicago.
