Need to demote non-global catalog domain controller
In our domain we have three sites with a dc at each site. Only 2 of the 3 dc's are gc's. I need to demote the dc that is not a gc to a basic file server. Aside from just running dcpromo, are there any precautions or best practices that I need to be aware of? Thanks.

Make sure your FSMO roles are running on another system. Make sure it won't break DNS if you're using AD integrated DNS. Also, make sure you have a backup of any certificates the DC is using. -

Cool. FSMO roles are running on one of the other servers and there isnt anything for this dc to resolve for dns since the office is now empty. Thanks. -

that should be pretty straight forward then."Check both the destination and return path when a route fails." "Switches create a network. Routers connect networks." -

Make sure you save some links to the procedures for cleaning metadata from AD after a failed DC demotion (incase it happens)

If you have multiple domains, you would in this case review the recommendation that a GC should not be the Infrastructure Master FSMO role holder and ensure your procedure wouldn't result in that unless you were going to have all DC's be GCs.
Infrastructure Master's should never be GCs unless it's a single domain or all DC's forest wide are GCs, as it causes replication issues.Good luck to all!
