RDP and NAV 2009 problem

Hi

I have a problem which I could only find hints to in this forum.

I have buyed and installed NAV 2009 on XP pro.

If any user connects locally - everything is fine and NAV's auto protect comes on :)

BUT!

If the first user to connect does it remotely via RDP on LAN or VPN (Hamachi) - NAV fails to start and the ccsvchst.exe is not listed under processes. :(

I understand it has something to do with XP's terminal services. Is there any way to solve this? - a lot of times I need to connect remotely to this machine (either LAN or Hamachi)
