I completely rebuilt the pool.
It's telling me that it can't use customization, so I told it not use customization. It builds and becomes available. I get logged into the client and choose the win 8.1 desktop. A screen comes up (which is usually your desktop), but it's black. It disconnects after about 10 seconds
There is really no tie to what I did previously. This is just a template I built from scratch, yesterday, with Win 8.1. So, everything is new. As far as I can remember, the pool settings are the same.
