Cause

Resolution

To resolve this issue:

1. Log in to the DNS server.
2. Clarify the DHCP reservation IP addresses and the associated host names as static DNS entries.
3. Add the missing entry in Reverse (PTR Record) Zone.
4. Open a command prompt and perform an nslookup of ESXi host names to confirm the DNS entries are working.
5. Boot the host using Auto Deploy.
   
   Note: In some cases with similar symptoms, Forward DNS could be missing. Make sure both entries, Forward (ARecord) and Reverse (PTR Record) Zones, are set.

Additional Information

The hostname may remain blank if the reverse DNS entry is missing.VMware ESXi 5.1 を Auto Deploy を使用してデプロイすると、ホスト名が空白のままになる
