DNS Update for ANF SMB Server & Alias

Whenever a new volume is provisioned under an ANF account, the SMB server does not resolve a reverse lookup, resulting in failure to create a PTR (Pointer) record in the Reverse Lookup Zone of a DNS server.

• Create a new alias name for the A Record

Validation

After the change is completed:

• Open Command Prompt

• Run the following commands to validate DNS resolution:

  nslookup [alias]
  nslookup [SMB server name]
  

Ensure both resolve correctly as per requirements.

Once the change is completed go to cmd prompt and do nslookup for the alias and the SMB server to validate it is resolving as per requirements.
