If you install logmein on a machine via RDP, when you then attempt to connect to it remotely (if it hasn’t been rebooted) you’ll get

This terminal server display is inactive” message.

If you’re using the free version you’re screwed and will have to wait for the PC to be rebooted.

If you’re using the Pro version or the Pro trial version then you should have Computer Management options on the right. Just reboot the machine and all should be OK. Haven’t found a work around if you installed the free version. This thread may shed some light though.

If you install logmein using

mstsc /admin

Apparently it works fine, but haven’t tested.
