CIFS Protocol Fails Intermittently

Hi

 

So I just configured this New NetApp FAS2750 and everything seems fine, except the CIFS/Volume Share.

 

It works only when I restart the CIFS service on the storage, and then I am unable to access the Volumes after some hours.

It runs on ONTAP 9.9.

 

Can someone help me with what I should do to fix this, I have added the domain credentials and included the DNS.

are you using NTP to keep time in sync between the cluster and the domain controller?

if the time difference is higher than 5 minutes, authentication will fail

The time is the same.

It's not even about authentication here per se.

One minute I am able to access the file share, ten minutes later I am unable to access the file share.

I have attached the error.

Any errors in the event log? Try running "set diag; event log show" and see if it logs anything. If not, a tcpdump may be needed. There are also some good suggestions on the articles on the KB site under this search string: https://kb.netapp.com/Special:Search?qid=&fpid=230&fpth=&query=cifs+share+not+accessible&type=wiki
