On SCVMM 2012 R2 While adding Loadbalancer with NSVPX-HyperV-10.1-119.7_nc, the Retrieve-LBSystemInfo test fails with Error 21426

Hi,

I'm trying to add Citrix LoadBalancer (NSVPX-HyperV-10.1-119.7_nc) in VMM 2012 R2 and on click of test button, only the "Retrieve-LBSystemInfo" test is failing with Error Code 21426 and exception as below. Whereas, rest of the test are getting passed.

Clik here to view.

Can anyone please let me know whether am I missing anything? FYI, I configured citrix lb as per blog:  http://kristiannese.blogspot.in/2011/07/load-balancing-and-cloud-computing.html
