 Hello Roman,  Appologies for delay reply... i got this issue resolved and was also a good leaning for me.   I was working on creation of a Demo server for my client and my setup was supposed to work with Forest Trust between client domain and my demo domain. Windows Hyper-V server on which all VDI were to be created was in client domain and later i found these issues werebecause of  Hyper-V and SCVMM were not keeping thier trust with each other as they are in different domains. As soon as i joined Hyper-V server to demo domain ,it started working although i already made client`s domain admin as local admin of the server and administrator in SCVMM.   My issue got resolved . thanks for your support and help   - Mohit Goyal
