AD dead in water after DC name change RRS feed

  • Question

  • I tried to replace my exsiting 2012R2 DC with a new 2019 DC and tried to rename the new to old by first changing the name the old server and then renaming the new server to the old server name, and when didn't work I change the old server back to it original name and now my AD structure is dead in the water, nothing can find the domain all network drives are now only accessible by the new name i gave the old server.

    I have striped all references to the this new name from our DNS and flushed it multiple time, but still whenever i run dcdaig it still trying to target the new server name. I also can't get netlogon to start.

    here's the out put from the dcdiag

    
    Directory Server Diagnosis


    Performing initial setup:

       Trying to find home server...

       * Verifying that the local machine mexsvr, is a Directory Server. 
       Home Server = mexsvr

       * Connecting to directory service on server mexsvr.

       * Identified AD Forest. 
       Collecting AD specific global data 
       * Collecting site info.

       Calling ldap_search_init_page(hld,CN=Sites,CN=Configuration,DC=mexbris,DC=com,LDAP_SCOPE_SUBTREE,(objectCategory=ntDSSiteSettings),.......
       The previous call succeeded 
       Iterating through the sites 
       Looking at base site object: CN=NTDS Site Settings,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=mexbris,DC=com
       Getting ISTG and options for the site
       * Identifying all servers.

       Calling ldap_search_init_page(hld,CN=Sites,CN=Configuration,DC=mexbris,DC=com,LDAP_SCOPE_SUBTREE,(objectClass=ntDSDsa),.......
       The previous call succeeded....
       The previous call succeeded
       Iterating through the list of servers 
       Getting information for the server CN=NTDS Settings,CN=MEXSVR3,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=mexbris,DC=com 
       objectGuid obtained
       InvocationID obtained
       dnsHostname obtained
       site info obtained
       All the info for the server collected
       Getting information for the server CN=NTDS Settings,CN=BACKUP-SVR,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=mexbris,DC=com 
       objectGuid obtained
       InvocationID obtained
       dnsHostname obtained
       site info obtained
       All the info for the server collected
       * Identifying all NC cross-refs.

       * Found 2 DC(s). Testing 1 of them.

       Done gathering initial info.


    Doing initial required tests

       
       Testing server: Default-First-Site-Name\MEXSVR3

          Starting test: Connectivity

             * Active Directory LDAP Services Check
             The host 393636c8-fd8d-45b5-8a36-4788029c5512._msdcs.mexbris.com could

             not be resolved to an IP address. Check the DNS server, DHCP, server

             name, etc.

             Neither the the server name (mexsvr3.mexbris.com) nor the Guid DNS

             name (393636c8-fd8d-45b5-8a36-4788029c5512._msdcs.mexbris.com) could

             be resolved by DNS.  Check that the server is up and is registered

             correctly with the DNS server. 
             Got error while checking LDAP and RPC connectivity. Please check your

             firewall settings.
