Performance center 11.52 host 'Non-operational' Error



In my PC 11.52 environment, LGs & Controllers are showing 'non-operational' while I start the load test. Verified the ALM –Pcserver—Controller—LG connectivity.


I’m getting are getting ping response, when I start the load test either Controller or LG goes to ‘non-operational’ mode.


As per hp knowledge base below items checked.


Verified there is no firewall in between.
UAC is disabled while logging in as IUSR_METRO. 
Enhanced IE Security is disabled on all the hosts
DEP is disabled on all PCS and Host systems.


Your suggestion much appreciated…
