OPC Services (DA & AE) do not take Service Status
I am working on a small virtualized system. Recently 2 new connectivities were added to the system however the Services related to OPC (opcda and event collector) do not take the Service status, and in consecuence OPC server do not connect either. Have you experienced or seen this situation before? Any ideas of what could be the problem?
Any ideas would be appreciated.

This is the expected result if the OPC server does not return OPC_STATUS_RUNNING on the periodic GetStatus() call performed by 800xA DA Connector/Event Collector.
A DA server's health can be probed with the built-in advdsopcclient.exe test tool. Connect and look for the Status indication.
There is no onboard tool for probing AE servers. Internally we circulate "Mr Crilfe/Joines" test tools on request. Speak with closest support center.
The reason for not entering service state is to keep clients "away" from a not healthy OPC server.
