https://www.experts-exchange.com/questions/22040753/AD-Replication-denied-by-Root-AD-server.html
I have 5 DCs in a WAN environment. Yesterday my Root DC stopped replying to one of those DCs. Now the servers do send/receive information but the Root doesn't replicate with the one DC anymore. The DC that cannot replicate states that the Root DC's RPC isn't available. All of the other DC's work properly and do not report any problems replicating.
I have tried removing and re-adding the site in sites and services, I have tried having that server added to a different site to see if it could replicate with any other of the DC's but that gives another error.
More information supplied at the question in the URL above.
Thank You

This problem has been solved.
It was a corrupted Riverbed Steelhead. It caused just enough of a transmission problem that RPC couldn't resolve to the troubled server.
I bypassed the Steelhead and I was able to add the server back into the Domain, DCPromo it back to a DC.
So if you use Riverbed Steelheads be watchful. If the RED light comes on, that means the Steelhead has a problem. Do NOT trust the passthru switch! Either get it fixed or bypass it until it can be fixed.
I have these on 3 of my DC connections, when they are working they work great! Now I know what to look for if my DC starts falling apart.
Thanks to all of those that tried helping!

What is Riverbed Steelheads?

Riverbed Steelheads are Netowrk caching devices. Basically they contain Harddrives and they cache the network files between sites. Obviously the HD size depends on the sites size.
For example, you have two sites that need to share a Finance Share. One site hosts the Finance share locally. Both sites have Steelheads installed. When users at the remote site access files from the Finance share, those files are technically copied to the Steelhead. They make changes to that file and the Steelhead send back only the tiny block changes. That makes the use of shared files much quicker as each user can open the files locally.
Keep in mind that the Steelheads are really using the files from the shared folder - so two users can't have the same file open and writable at the same time similar to a LAN.
