We have had a number of domains which were on our WAN, ER GRR CR GPR and a couple others. We've worked that down to ER and GRR. I thought we had all of the ER DC's shut down, and when i go to remove a domain on the metadata cleanup area, there is nothing there to remove.
However when i go to a pc to login and i choose the domain drop down, it still shows ER on some pc's and servers. It also shows in aduc under the "In:" drop down.
Does that probably mean i've missed shutting down a dc somewhere?
