I'm now in full rebuild mode after last weeks unfortunate RAID incident.

After installing Citrix Desktop and setting all my parms back up, I got

“The desktop you are trying to open is currently available only to administrators. Contact your administrator to confirm that the correct settings are in place for your client connection.”

After some digging around, I came across this Citrix posting that was exactly the problem.

I had the Citrix Connection set to "Server", it needs to be "Published Application".

Too bad the error message itself didn't actually mention that. But it's hard to find too much fault in that.
