I am trying to promote a member server to DC (Windows 2008 Std. r2) dcdiag passes but dcpromo fails; This is the first server in a new site of an existing domain.
dcdiag /test:dcpromo /dnsdomain:[DomainName].lo
Starting test: DcPromo
The DNS configuration is sufficient to allow this computer to be promoted
as a replica domain controller in the [domainName].local domain.
Messages logged below this line indicate whether this domain controller
will be able to dynamically register DNS records required for the
location of this DC by other devices on the network. If any
misconfiguration is detected, it might prevent dynamic DNS registration
of some records, but does not prevent successful completion of the Active
Directory Domain Services Installation Wizard. However, we recommend
fixing the reported problems now, unless you plan to manually update the
DNS configuration is sufficient to allow this domain controller to
dynamically register the domain controller Locator records in DNS.
The DNS configuration is sufficient to allow this computer to dynamically
register the A record corresponding to its DNS name.
......................... [ServerName] passed test DcPromo
When I run dcpromo I get the following error;
Active Directory Domain Services Installation Wizard
The Wizard cannot gain access to the list ofdomains in the forest.
This condition may be caused by a DNS lookup problem. For information
about troubleshooting common DNS lookup problems, please see the
Following Microsoft Website.
The error is:
The RPC server is unavailable.
All RPC services are started in services.msc
ran ipconfig /flushdns and ipconfig /registerdns on both servers. The A record for the server I'm trying to promote is there on the primary DNS server.
created in/out rules in Windows Firewall allowing traffic between subnets. Can ping by name and IP. Have Googled Technet for troubleshooting.
Looking for ideas.
