Vista - migrating user account

Hi All: I have Vista Business sp1 on a workstation, which is part of 2008
domain. The box had been previously running XP pro sp3, but I did a fresh
install. I had been logging into XP as an admin.

When I first installed Vista I was prompted to create a user account, which
I did, and then manually migrated over my documents, imported my Outlook
Express psts into Mail, etc. So I'm logging in as a local user. I joined the
computer to the domain and everything is fine, except I need to authenticate
on the domain whenever I need to do something like open a server share.

I'd rather log onto the workstation as a domain user, but I realize if I do
this I will lose all the settings in the local user account. Is there any
easy way to migrate the settings from a local user account to a domain user,
without manually copying everything folder by folder?
