I have a small problem with one of my DCs.
I recently built a new DC using a Dell 2850, running Windows Server 2008 R2 x64. I was given a project to upgrade all our training infrastructure to x64 bit.
The DC has been built and works okay, however I'm having real difficulties with DNS, AD Replication.
I'm unable to do a replication to the new DC, as it complains about RPC errors. I know the IP addressing that I've used is fine as the server can be pinged from any of the other servers.
I ran the DNS tests from a command prompt but to no avail. I have attached both files as well to make it easier to see what I have done.
From server 1 I can create an object in AD and have it replicate successfully. However it does not work the other way. I am going to demote the old DC and transfer its roles, DHCP etc...
I know there is a Windows Migration tool in Server 2008 to do this but I am not clued up in Powershell well enough to do this yet.
So everyone is clear, the setup currently is:
DC1 - Server 2003 R2 (Schema Master etc)
DC2 - Server 2008 R2 x64 (Normal DC/GC server)
Any help would be appreciated.
