问题：

最初，我收到了SVR记录丢失错误，因此我添加了一个特定的SRV记录_ldap._tcp.dc._msdcs svr，还尝试了通配符SVR。但是当尝试加入时，我最终遇到以下错误:

Note: This information is intended for a network administrator. If you are not your network's administrator, notify the administrator that you received this information, which has been recorded in the file C:Windowsdebugdcdiag.txt.



DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain "mydomain.com":



The query was for the SRV record for _ldap._tcp.dc._msdcs.mydomain.com



The following domain controllers were identified by the query:


mydomain.com



However no domain controllers could be contacted.



Common causes of this error include:



- Host (A) or (AAAA) records that map the names of the domain controllers to their IP addresses are missing or contain incorrect addresses.



- Domain controllers registered in DNS are not connected to the network or are not running.

答案1：

我建议在Google VM上查看Netsetup.log文件错误，这导致额外的故障排除步骤，你也可以运行 PortQryUI(Active Directory测试)来确认你的Azure VM和Google Cloud VM有相同的结果。
