merging Vista user profile back with domain account - SBS problems

Hello,

I started by installing Vista Ultimate and created 3 user accounts on it +
my own admin.

Then I installed a SBS2003 domain and joined the VIsta PC to it. Here are
my issues:

1) when I used the http://myserver/connectcomputer site to connect the PC, I
could not associate the new domain user account to the Vista local user
account. Any way I can merge them after the fact ?

2) each time I log in using one of the 3 accounts, I get the SBS client
setup that requires elevation run again and again. How can I get rid of
that ? BTW, SBS joined the users as local admin but I reverted them back to
user account.

3) before the installation of SBS, I was using parental controls to manage
the 3 Vista accounts. Now this is gone...any way of getting it back on a
domain ? I am using my kids as guinea pigs but I do like the features of
parental control and would hate to loose it on my SBS domain.

I have seen that there will be a new SBS client package that will be
released at the end of january for Vista and Office 2K7. Will that resolve
#2?

Thanks
