We had a 2003 AD domain (1 domain controller)
We have run adprep-->dcpromo the 2008 R2 DC-->dcpromo the 2003 DC to remove it from the domain.
While running the dcpromo on the 2003 DC to remove it from the domain, the process timed out because netlogon services could not be stopped. Running dcpromo again worked successfully and the 2003 DC is now a member server. The domain is in 2003 Mode and we plan to change it to 2008 R2.
The domain controller was automatically removed from the Domain Controllers OU but we found that there are still remnants behind in DNS (eg ldap & kerberos SRV records)
In addition to that, the 2003 DC sill appears in site & services.
We haven't looked at other locations ...
Any suggestions/links on cleaning it up ? Is it a matter of removing the DNS entries manually and deleting the entry under sites and services ? anywhere else we should look ?
