Hi Gleb,
Many thanks for your reply, much appreciated!
The RegisteredOwner was already there, also with a value, but I had to add RegisteredOrganization and a value. I restarted the computer and tried to access it remotely, but unfortunately with the same result as before.
Just to have it ticked off, I also did the same check in the client. Both strings where there, but I added a missing value for RegisteredOrganization.
Restart and new test, but I'm sorry to say that there was no difference in behaviour.
Anything else I could try?
