We are currently experiencing the following error under the Server Manager > Manageability on Two of our Windows Server 2012 R2 Servers. Online- Data retrieval failures occurred.

I can't find any information in the event viewer that relates to this error. Does anyone have any suggestions?

Kind Regards

Hi TParky,

This error most time occur when the firewall configure incorrect, please try to disabled firewall on all this servers, then try again. This indicated the Server Manager cannot get event data from the target server. The user might not have access rights to the target server event log, or event log files might not contain valid data.

For some roles and features (Hyper-V, Print and Document Services, AD LDS), this error can occur after installation, but before required post-installation configuration has been completed. The error is resolved after post-installation configuration is complete.

This error can also occur if specific roles and features have been installed, but not yet configured. The following underlying error messages are examples of known cases where a role, role service, or feature requires post-installation configuration to clear the error.

Events from Virtualization.Events.xml could not be enumerated. (This error is cleared after required post-installation configuration for Hyper-V is completed.)

 Events from PrintServices.Events.xml could not be enumerated. (This error is cleared after required post-installation configuration for Print and Document Services is completed.)

 Events from ADAM.Events.xml could not be enumerated. (This error might be cleared after required post-installation configuration for Active Directory Lightweight Directory Services is completed.)
