I am hoping you can help me.
I have a server that is hosted in our cloud that I am trying to promote to a DC. This is connected to our Active Directory through a ipsec vpn tunnel. The machine was successfully added to our domain, I can ping both ways and it also resolves.
When I try to dcpromo I get two messages.
1.Warning - a delegation for this dns server cannot be created because the authoritative parent zone...
it says I can ignore the warning and create it later. When I look to create it I can only create a sub domain which I don't want to do.
I hit next but would feel better if that wasn't there.
2. goes through and then at the end errors with RPC is unavailable:http://blogs.technet.com/b/abizerh/archive/2009/06/11/troubleshooting-rpc-server-is-unavailable-error-reported-in-failing-ad-replication-scenario.aspx
I did the report on the above and it appears that port 88 and port 389 where blocked but when I did the report just on those ports they said they were open.
I am at a loss and have been looking at this too long.
Any help would be appreciated, this is my first time setting up a server and extending my AD.
