This article describes what you should do if you receive a message stating that the Replay Core is unable to connect to the Replay Agent.
If you receive a message stating that the Replay Core is unable to connect to the Replay Agent, then protection of that agent machine is not functioning properly. Follow the suggestions listed below to troubleshoot the issue.
Follow the suggestions below to troubleshoot the issue.
The account used to install and execute the Replay Core service can be a local administrator account or a domain account that has administrator privileges on the server. To protect servers across domains, there are two options:
The Replay Core service does not require domain administrator privileges, only a domain user account with local administrator privileges.
NOTE: Replay can install using a local administrator account. However, when protecting application servers, many tasks require domain user privileges. In this case, we recommend installing Replay using a domain account that is a member of the domain administrators group.
If the credentials are invalid, the Replay Agent and Replay Core services will not be able to authenticate.
To protect Exchange workloads, the Replay Agent service must run under an Exchange administrator account, which must also have local administrative privileges on the Exchange server.
It is recommended that the service account is not a domain administrator account or administrator account. The account should be an Exchange administrator for the Replay Agent and should have local administrative privileges for both the Replay Agent service and Replay Core service.
For proper email restore operation (email restore using MailRetriever), the account used to launch MailRetriever must have full control permission granted on the database you will be performing restores to, including “send as” and “receive as” permissions.
