The traditional fix to this in XP and Server 2003 was to use the MSTSC command with a /console flag (or /admin for later service packs) to carry out console mode. However this does not work anymore. So I did a little research...
It's stated on Guidance's website that "EnCase is not officially supported running over Remote Desktop due to the manner in which the Remote Login Account is given access to the System devices". A discussion with one of their support representatives and some messages on their forum in fact further confirmed that Encase has never supported RDP (in any of their releases).
- Disable Fast User Switching, Disable User Account Controls, start up your instance of Encase Forensic, open your case up/start your processing. THEN, remote in using the "mstsc /admin" command and log in as the same user you have an instance of Encase already running under. This works.
- Now, you can always use a VNC or PCAnywhere application to accomplish this as well. Works like a charm.
