A couple users are trying to access the virtual server via a web browser. Their accounts have "Full, Modify, View, Remove, Change, and Control" permissions. They can access the link.
User 1 can see the 4 virtual machines running (small screen captures), but when she tries to access the host she gets a black screen.
User 2 cannot see the 4 virtual machines running (small screen captures), but he can access the link.
Two other users can access the link just find an click on the virtual machines just fine.
