Remote session under W7

[DIDE]

Hey,
Since 2 weeks, we have in our network 10 W7 PC's... the other ones are XP's (100 PC's).
When we do a remote control via Lansweeper it takes a very very long time before we can access the PC (I see some actions like disabling old remote control service etc...).
We do not have this with XP PC's... what is going wrong?

Can you try starting the remote registry service on the windows 7 computers.

[DIDE]

Yes, all works but a thakes a very long time before i have really the remote screen before me...

[Hemoco]

Is the remote registry service running on these computers?
Is the firewall configured correctly?
