-

i have 3 servers.

server - windows 2012 data center hyper-v role
server b - hyper-v 2012 server
server c - windows 2012 data center smb server

all servers in same domain. both server , b configured cifs delegation server c. using server a's hyper-v management console manage server b's hyper-v service. smb share created on server c full access permision both server a, b , user domain admin.

here problem have. when try create vm on server b via server a's console , specify storage on smb share on server c, following error.

[window title]
new virtual machine wizard

[main instruction]
server encountered error while creating t2.

[content]
operation failed.

failed create external configuration store @ '\\server-c\hypervshare\t2': general access denied error. (0x80070005)

[expanded information]
operation failed.

user 'domain\admin' failed create external configuration store @ '\\server-c\hypervshare\t2': general access denied error. (0x80070005)

any advice appreciated.

you doing double hop in case, running a constrained delegation issue.

you being denied because between console on server , server b you.  server b server c attempting you, but server b can't impersonate you.
