asked on 

Moving OUs in ADUC not reflected in GPMC ??

I have created a set of Computer OUs.
There is a top-level Computer OU for the company/domain.
There are 3 site-related Computer OUs at the next level down.
PLUS, one more Computer OU at this same level for "test computers" that are put there on a transient basis.
Domain Computer OU
  Site 1 Computer OU
  Site 2 Computer OU
  Site 3 Computer OU
  Test Computer OU.

After having used this structure for a time, I realized that I always do this:
1) put test computers into the Test Computer OU and link a new GPO there only.
2) Since Site 3 is the smallest, link the new GPO also to Site 3 Computer OU.
3) With good test results, add a link to Site 2 Computer OU.
4) Finally, add a link to Site 1 Computer OU or, alternately remove all the links and add one to Domain Computer OU with the same effect.

I hope that sounds reasonable enough....

Now, I figured that moving computers in and out of Test Computer OU might be a bit of a waste of time if I were going to just start yet another test.
So, I thought it might be helpful to Move Test Computer OU into Site 3 Computer OU and just leave the test computers there.

First, I removed all of the computers out of Test Computer OU - putting them into the other 3 OUs.
Next, I unlinked the current testing GPO link from the Test Computer OU.
Next, I MOVED the Test Computer OU into Site 3 Computer OU.
However, the Test Computer OU didn't show as moved in GPMC.  ????
Why might that be?
Restarting the DC didn't fix it.....

(I did get it fixed but not without some trepidation).

Why might that be?

check your domain controllers to make sure your intersite replication is working
start with that

whatever DC you are connected to in ADUC, connect to that same DC with the GPMC and see if the changes are there; if so, you might have a replication issue
OU will always have precedence
remember the acronym LSDOU

Thanks folks!

I should have been clearer.  I was doing all the work on one DC directly.  Not with an ADUC interface on a workstation.
The GPMC was likely open when I moved the OU.
Refreshing, closing, opening, etc. seemed to do nothing.... either on the GPMC or the ADUC interface..
I didn't look at the other two DCs as I was working on one.  And, I'm the only one who would have been doing things like this.  So, I expect the other DCs were "watching" at the most.

The fix was to delete the OU entirely and start over.
