I have recently setup a CIFS Server by following this guide https://library.netapp.com/ecm/ecm_get_file/ECMLP2
- I can access the CIFS endpoint from windows explorer by typing the IP: \\10.111.112.7 works.
- I cannot access the CIFS endpoint from Windows Explorer by specifying the NetBios name: \\ServerS7 doesn't work.
- I cannot resolve the NetBios name from a windows workstation: nbtstat -a ServerS7 doesn't find anything
- in the OnTap CLI,
::> vserver cifs nbtstat This table is currently empty.
To me it looks as if the NetBios/WINS service on the Netapp that should respond to NetBios queries is not running/doesn't accept requests. I've tried to recreate the CIFS Server a few times now (by following the previously mentioned manual) but that doesn't help anything.
Here are some more configuration infos:
::> vserver show -vserver svm_cifs Vserver: svm_cifs Vserver Type: data Vserver Subtype: default Vserver UUID: 15dac770-ff50-11e6-9afb-00a098c6d0c7 Root Volume: svm_cifs_root Aggregate: AGGR_01_Node1_Links_SAS NIS Domain: - Root Volume Security Style: ntfs LDAP Client: - Default Volume Language Code: C.UTF-8 Snapshot Policy: default Comment: Quota Policy: default List of Aggregates Assigned: - Limit on Maximum Number of Volumes allowed: unlimited Vserver Admin State: running Vserver Operational State: running Vserver Operational State Stopped Reason: - Allowed Protocols: cifs Disallowed Protocols: nfs, fcp, iscsi, ndmp Is Vserver with Infinite Volume: false QoS Policy Group: - Caching Policy Name: - Config Lock: false IPspace Name: Default Foreground Process: -

After spending more than a day on this issue, I've run out of ideas on how to debug this.
Do you have an idea on what could be the problem?

Are you sure the client and vserver both on the same subnet? do they both have the correct subnet mask?
if you do need it to travel across subnets. you probably can set some IP forward rule on your router to allow that.
i just tested it. having a server in the same subnet of two of the SVMs LIFs, both not registered in DNS. and as you can see. the two LIFs responded to the NBNS request, each with all the IPs available on the SVM (Running Ontap 8.3.2, all the config out of the box. no customization)
.53 = test server i used
.255 the broadcast address
.116/117 LIFs of SVMNAS01PR.
