  1. Thanks for this brillant piece of information and we were actually looking for this information for our implemetation purpose.

    Do post interesting article like this.

  2. I’ve been trying to setup GALSync w/o a luck.

    On your step #13, you are entering the source domain/forest information (a.com), correct?

    And on step #14, you are seeting the target domain “k.com” under select directory partition window.

    How do you see the target domain on #14? I can only see the source domain that I entered in step #13.

    Any help would be greatly appreciated =)
