Active Directory "Log on to" restriction and Vista RDP

Hy,

In an Active Directory environment I configured "Log on to"
restriction to some users. Let's asume that user A is restricted to
log on only on Computer A. User A is a standard user. User A is also a
member of the "Remote Desktop Users" on the local computer (computer
A).Computer A is running Windows Vista.
After setting up the "Log on to" restriction remote desktop from
anywhere to computer A using user A doesn't work anymore. Any ideas if
there is a patch or smth for this ? (Spent 2 days searching this on
google and didn't found anything.) Note that this behavior occurs only
on computers running Vista. XP clients works fine.
