Hello,
So I've been using vRA 7.3.1 to deliver Windows 10 x64 jump boxes to users. I was upgrading the image and it forced me to RS5. I didn't see any issues during the setup, however when I tried to create a new image it fails. It appears to clone the machine, but when it goes to use the Guest OS customization in vCenter it never does it. Never joins the domain or renames the guest OS. I tried this also in vCenter directly and it didn't work either. So I tried to create a new image starting with RS5 as the base image. I just installed the OS and VM tools and that was it. What I wind up seeing in vCenter is the machine cloning, then it shows the customization is started, then the machine power on. If I wait about 30 minutes it seems then it actually does join the machine to the domain. However when I was using vRA and even RS4 this process was maybe 15 min tops, even with the customization after the domain join, so something is wrong here. I'm using vCenter 6.5 and I just patched it to update 2uf to see if that would make a difference, but it didn't. I'm not sure if I'm missing something else, if I need to go to vCenter 6.7 or what, but this is blocking me from handing off this project to someone else. Any help is appreciated.
