Resolution

1. Login to vCenter Server Appliance with root credentials via SSH.

3. Run the below command to set the DNS servers:
   
   com.vmware.appliance.version1.networking.dns.servers.set --mode  static --server <DNS Server IP Address>
   
   Note: When adding multiple DNS servers, enter the next IP address directly after the comma (,) following the first DNS Server IP address, without including any spaces.
   
   Example: When DNS Server IP Address 1 is AAA.AAA.AAA.AAA and DNS Server IP Address 2 is BBB.BBB.BBB.BBB
   
         Command> com.vmware.appliance.version1.networking.dns.servers.set --mode  static --server AAA.AAA.AAA.AAA,BBB.BBB.BBB.BBB
