Question

ERR2:7711 Unable to retrieve the DNS hostname for the migrated computer

Answer 1

Hello AdminAzure,

This error typically occurs during Active Directory migration or domain join operations when the target system’s DNS hostname cannot be resolved. Below are a few steps to help troubleshoot and address the issue:

1. Verify DNS Registration Ensure the migrated computer has successfully registered its hostname in DNS. You can check this by running:

nslookup <computername>

If the name does not resolve, confirm that the system is configured to register its DNS records automatically.

2. Confirm Network Connectivity Make sure the migrated computer can reach the DNS server and that there are no firewall or routing issues blocking name resolution.

3. Check DHCP and Static IP Settings If the computer uses DHCP, verify that the DHCP server is configured to update DNS records. For static IP configurations, ensure the correct DNS suffix is applied.

4. Review AD and DNS Replication Confirm that Active Directory and DNS replication are functioning correctly across domain controllers. Use repadmin /replsummary and dcdiag to identify any issues.

5. Manually Create DNS Record (if needed) As a temporary workaround, you can manually create an A record in DNS for the migrated computer to allow resolution.
