  Thanks Dave for your Reply
  verification of prerequisites for domain controller promotion failed. The NetBIOS domain name 143 is a number .The name may not be a number
  
  Instance domain name : 143shanth.com , in case of website it works but in case of AD configuration NetBIOS has error. Please Suggest thanks
