Frank,
What is going on with this. I just tested this and have had no issues.
What were you trying to do ( what fields ), what did the GUI tell you ( 16
attributes were successfully updated ) and what really happened?
Did you select a Domain Controller ( have to or it will not go on and will
prompt you )?
Did you select a Domain Controller in the Site in which you are sitting (
could simply be waiting for AD Replication )?
Did you make sure that you selected at least the Users check box ( you have
to have at least one check box )?
HTH,
Cary
