To resolve this problem, manually grant sufficient access permissions to the WINS service. To do this, grant the Full Control permission to the local service account for the new WINS database location in Windows Explorer. You can also run the following command at a command prompt:
icacls new WINS database location /grant "NT SERVICE\WINS:(OI)(CI)(F)"Note
When you try to back up the WINS database to another target folder, you have to grant sufficient access permissions to the target folder also. Otherwise, you may receive an "access denied" error when you perform the backup.
