Citrix recently released desktop server v1.0. I finally got some time to try it.
I get a general error the first time I tried over RDP session. Then I tried again. This time I installed it over a RDP console session (mstsc with /console option). And the installation worked. I am not sure if it is a problem with installing it on regular RDP connection yet. But it is safer to install on a console session anyway.
The CDS team did a great job of simplifying the single server install. The install only asks some simple questions and the rest is fully automated including Database and web interface installs. It is much easier than desktop broker installation.
One thing to note if you install over RDP session, you may not be able to RDP to it after the server is rebooted if you haven configured a license server yet. I had to finish the installation at console.
