We have a Xenserver running version 6.5.0-90233c. We have a seperate domain controller. We loaded XenDesktop Express (5.6) on a windows server 2008R2 VM. We also created a Widows 7 master image and connected both VMs to the domain. When we try to create a pooled infrastructure, the creation of the vms fails and says unable to connect to remote server. It works if we do a dedicated connection to the master image. We really wanted 5 pool machines though. Can anyone fix this?
