RNRP node status must not jitter between up/down!
Workplace launch is dependent on "up" between servers and clients.
Please examine your network, settings, etc!
The root cause is often some network problem, e.g. some IGMP or multicast setting not in line with what the 800xA Network User's Guide list as required.
In early 5.1 there was a problem with RNRP (v 3.17) that could lead to intermittent *netw* up/down - but I assume you are not on any early 5.1 version?
Also, "Receive Side Scaling" feature on NIC driver may fool RNRP to incorrectly detect loop and close network ports. Disable RSS if you find it enabled on any of the involved NICs.
There is also a "known problem" with system stability if a service is left incorrectly configured so that it is continuously restarting over and over again, e.g. an OPC DA Connector service provider trying to connect a non-existent, or not running OPC DA server. Delete or disable such continuously restarting service providers and reboot the affected server(s).
But start off with using the RNRP Utility/Fault Tracer's first command:
"1. Search own network for nodes with problems or errors".
Get those errors corrected, clear the errors, report the search (expect no errors to be listed) and see where it takes you.
