Hi – I can RDP into my RDWeb server with no issue, I can access the RDWeb browser page login and login just fine and it shows all my remoteapps (MS Word/Outlook/PowerPoint/Explorer/RDP). When I launch one it prompts for credentials, I have tried the domain admin credentials as well as user credentials for testing, and the remote app launches the RDP session, but right after it says Preparing your Desktop it goes straight to Logging Off and closes out. I do have a SSL cert that will expire 1-20-15, but that shouldnt be a factor right now I wouldnt think.
Someone just posted this, which sounds like your issue:
Did you install the dec windows patches already?
