Configuring DNS in Server 2008

I downloaded a trial version of Windows Server 2008 prior to ordering Small Business Server 2003 through TechSoup.  After installation, I ran DCPROMO but had some problems, so demoted the server.  I ran DCPROMO again, but get 4 error messages as server appears to be looking for other servers.

Ran ntdsutil, but no evidence of others servers.

Two of the error logs are attached.  Other two are identical.

Tried to change clients from Workgroup to domain, but get error that domain server can't be found.  I can ping the server from the client.

Clearly a serious cockpit problem on my part.

Is VOLGROUP.COM the domain name you used duringDCPROMO of your win2k8 server to a domain controller? Also, what problem did you get during DCPROMO? It seems like you may not have installed your DC properly. See if this reference help: http://technet.microsoft.com/en-us/library/cc772558(WS.10).aspx

When you join clients to the domain with error, can you ping the domain name(both netbios name as well as fqdn)?

When I first tried to promote to a domain, I used VOLGROUP.COM.  I then demoted and tried to promote again.  This time using VOLGROUP.NPL.  Seems that VOLGROUP.COM is still around.  That's what I'm trying to get rid of without starting over from scratch.

I can ping AARP as well as AARP.VOLGROUP.NPL.

Attached is to dcdiag.txt file when trying to change client from workgroup to domain.

Only solution I found was to delete the entire installation and start over.  Couldn't find a way to purge O/S of past FQDNs.  They seem to be considered DCs that AD is looking to for info.
