GCP - Compute Instance running active directory DNS config and sometimes failure on client startup

I maintain an infrastructure with 2 Domain Controllers (DC) and other servers for Remote Desktop Services (RDS) infrastructure. The 2 DC run also DNS server for local AD domain, so on the other servers I will use the DC IP as DNS Server Address. In the RDS infrastructure there are some Remote Desktop Session Host (RDSH) that overnight are turned off. Sometimes a random server fail at startup, in the event viewer I can't find specific error, but all event show a network error, more specifically a DNS error, for example:

Log Name: System Source: Microsoft-Windows-Time-Service Date: 19/02/2019 08:20:52 Event ID: 134 Task Category: None Level: Warning Keywords:
User: LOCAL SERVICE Description: NtpClient was unable to set a manual peer to use as a time source because of DNS resolution error on '”metadata.google.internal,0x1'”'. NtpClient will try again in 15 minutes and double the reattempt interval thereafter. The error was: No such host is known. (0x80072AF9)

Or in the application event

Log Name: Application Source: GCEMetadataScripts Date: 19/02/2019 08:20:51 Event ID: 2 Task Category: None Level: Error Keywords: Classic User: N/A Description: ERROR: 2019/02/19 08:20:51.435448 main.go:258: GCEMetadataScripts: ERROR main.go:258: error connecting to metadata server, retrying in 3s, error: Get http://metadata.google.internal/computeMetadata/v1/instance/attributes/?recursive=true&alt=json&timeout_sec=10&last_etag=NONE: dial tcp: lookup metadata.google.internal: getaddrinfow: The requested name is valid, but no data of the requested type was found.

So I think that mi machine can't resolve internal google domains using MS DNS.

Is there a way to manually configure google internal DNS in the instance? What are IP addresses of Google Internal DNS?

Thank you all.
