Migration Wizard concerning Notes

[Noobie_SMS]

I'm using the one step process as outlined in the MS Integration document,
but I hit on a little snag. I get through the wizard fine but at the
migration step for selecting the "Container for New Windows Account" I tried
expanding the domain and it doesn't do anything. I click on the plus tab
nothing double click nothing, and double click on the domain icon and it
still won't expand to show the container of the domain. Any suggestion is to
why this is happening?

Thanks in advance
