Resolution

  • We should fix the issues with admin user configured for file services within AD domain. The issue can be with password, permissions and change of admin user name.

  • If the AD admin user used  for vSAN file services has been renamed, please revert the changed admin name back to original. 

Fixing the admin user issues are expected to allow the file share creation.
