Is it possible when using RD to allow the remote machine to see the session? Right now when I remote into a machine on the company domain it shows the login screen during the course of the session. Unless I missed it, I don't see an option to change that behavior.
users can send in a remote assistance request but ive honesly never seen anyone use that feature really, from looking at it the implementation is poor.
if you have a few machines to get to regularly try logmein or something (under 10 is free free, not sure if theres a technical business limitation or not though), if you have a one-off here and there use teamviewer or crossloop, if you need it a lot then there are lots of products with an agent or agentless install that will give you screen sharing. VNC is ok, logmein, goverlan, dameware, teamviewer, kaseya and some others can offer this as an option with varying price ranges depending on your needs/budget and can also offer reporting/inventory/remote config/management/software updates and such
