New SCVMM Server is not recognizing the Hyper-V Hosts

Hello Everyone,

I setup a new SCVMM Server in our domain and this setup is not recognizing the Hyper-V Hosts within our Domain and instead its picking up few VM's (not complete list). One time it recognizes a set of servers and another time it will pick up a different set. I am pretty sure I missed something here. Can anyone help me out on this issue! Or any inputs here for how to set up brand new SCVMM Server setup also should work for me :-)

Specs:

SCVMM Server Version: 2012 SP1

Hyper-V Hosts Version: 2008 R2

Thanks

Vikram
