Why below  errors are coming in nas check.    check_CIFS_file_server_configuration   Warning     external   <BR /> <BR /> * <STRONG>server_2: The DNS server is not up-to-date. The IP address 10.105.2.115 of the CIFS server 'vwvickfnas01.apac.vwg' is not registered in DNS. Depending on the configured update mode (parameter dns.updateMode), the issue may concern a manual update that has not occurred on the DNS server or a Kerberos problem. </STRONG><BR />    <BR /> If the DNS update mode is manual (dns.updateMode=0), update the IP address of the CIFS server in the DNS manually. If not, try a 'server_cifs' command to figure out the problem with the FQDN.
