Active directory objects not syncing with server?

One of my coworkers added some of our soon-to-be-imaged machines to our OU in our organization’s active directory.

On his screen in his management console, he had the computers added and was able to double click on them and view properties.

However, when I opened my management console, they were not there. I added a test computer object to our OU from my console, and he was able to see it. But I was unable to see the ones that he had created.

My coworker both have rights in that OU as administrators, so we’re able to add and delete.

Any ideas as to what’s causing this?

Thanks in advanced 🙂

PS – the server is Windows Server 2008 R2, and both of our pcs are Windows 7 with Remote Server Administration Tools installed and enabled.
