Technically, this should be in the DameWare product forum
Check out this thread; specifically the post a couple of entries down "by bryan on Tue Nov 20, 2007 11:19 am"
"The need for Permission (Accept/Decline) when connecting to a remote machine using the MRC software is primarily based upon what right you have within the O/S security on that remote machine. However, the current Desktop State on the remote machine, and also some settings within the software itself are also factors in this equation as well.
Therefore, the very first thing you need to examine is what rights your credentials have within the O/S security on this remote machine, Administrator or non-Administrator, and by non-Administrator this refers to everyone that is not a member of the Administrators group on that machine either directly or indirectly via some other group membership."
"The only time a non-Admin could possibly connect without requiring permission would be if the remote machine was currently at the Logon Desktop or Lock Screen. "
In the case where "A non-Administrator tries to connect and the remote machine is currently at the Logon Desktop or Lock Screen, the non-Administrator will only be allowed to connect if the "Disconnect if at Logon Desktop" feature has been disabled (it is enabled by default). If it's enabled, their connection request will be denied with a dialog box stating: "The remote machine is currently at the Logon Desktop. Your credentials do not allow you to access the remote machine at the current desktop state".
