Offer remote assistance

[Marko]

I'll jump right to the case. Offer remote assistance from Vista to XP
doesn't work. Through invitation file sent from XP Vista can connect just
fine.
Error I'm getting is:
Your offer to help could not be sent
Check the following:
Do you have correct permissions on the remote computer?
IIs the remote computer turned on.
Is there a network problem?

I've administrator rights on both computers.
XP to XP offer works just fine so I doubt that this is connected to GP.
