How do you transer password when the login pre-exists though? 

You would have to script out any exisiting roles, then drop these, then drop the login then add the logins and password thoguht the revlogon script, reapply the roles then fix up any orphaned users??!

We have our users change every 30 days so they could not remeber their inital password from ages ago..

Any thoughs appreciated..
