I have a stand-alone server that is host to a web application. I've created a new domain (new forest) for security as well as preparing for additional servers. I have a problem where it looks like dns svr records were not created correctly during the DC Promo operation and now there appears to be connectivity issues. Dcdiag /fix returns the following error:
Testing server: Default-First-Site-Name\HOST1
Starting test: Connectivity
The host 5c533dbd-a226-42e6-8968-b6c5296c08fe._msdcs.mydomain.com could not be resolved to an IP address.
Check the DNS server, DHCP, server name, etc.
Got error while checking LDAP and RPC connectivity. Please check your firewall settings.
......................... HOST1 failed test Connectivity
What is the best way to resolve this?
