Importing GPO RRS feed

  • Question

  • I am trying to import 2 (or more) GPO's from a domain so I can compare the baselines. I did Import "GPO Backup Folder" selected the backup and it is good. Then I do the same thing with the second and I get a message "An item with the same key has already been added". Selecting OK bring the screen "Object reference not set to an instance of an object". I can rename the GPO in the GPMC and back it up again and the same thing. Where is this key stored so I can rename it or bypass it? How can I get around this error?

  • For anybody that gets this error it is because there are 2 equal lines in the group policy. In my case I had 2 lines for the file security defined twice and it threw this error.

  • How do you find where the equal lines are?

  • I took the inf file and did a sort with a unique and compared it to the original file with a diff and got the duplicate lines.
