I had two domain controllers in a domain. Both of them were Windows Sever 2008 x86. One of them rolled over and died. I have another server that I want to promote to a domain controller. It is a Windows Server 2008 R2 x64 box. I have to run adprep /forest prep and adprep /domain prep because of the R2 difference. I have taken a full backup of the lone domain controller and then other domain controllers in other domains within the forest. I am really nervous about doing the adprep because of the article I am following entitled "Running Adprep" http://technet.microsoft.com/en-us/library/dd464018%28v=ws.10%29.aspx#BKMK_PrepFP For the record the domain in question is the forest root domain to which all other domains trust.
The reason(s) I am a apprehensive is
1) I'm concerned that because the other DC is dead the Adprep is going to go off into never never land trying to make contact with it.
2) under the preparing to run adprep /forestprep section one of the bullet points states: If you boot the schema master on a private network, it will fail initial
synchronization unless you also place a second domain controller on the
same private network. --uh, I'm trying to make a second domain controller, so how do I get past this? Maybe I'm misunderstanding what is meant by private network? This is one domain within a forest of a total of 4 domains. Each domain has 2 domain
controllers.
3) under step 5 of preparing to run adprep /forestprep it says to run
- Run the following Repadmin.exe command to ensure that replication is working throughout the forest:
repadmin /replsum /bysrc /bydest /sort:delta
All domain controllers should show 0 in the Fails
column, and the largest deltas (which indicate the time that has
elapsed since the last successful replication) should be less than or
roughly equal to the replication frequency of the site link that the
domain controller uses for replication. The default replication
frequency is 180 minutes.
Mine fails with "Repadmin experienced the following error trying to resolve the DC_Name: /bydest Error: An error occured: Wind32 Error 8419(0x20e3): The DSA object could not be found. What the heck does that mean and is it a show stopper?
The last thing I want to do is make things worse than they already are. If anyone has any ideas about this or can point me in a direction to find answers I'd really appreciate it. I'n only on page 4 of 12 in the document so who knows what other questions I'll have in a short while.
