The CIFS share may become unavailable after 15 or 30 minutes or even 2 hours after. The time after the issue might occur varies lot.    







Restarting cifs via the command "cifs restart force" might not help. Disabling and enabling CIFS using the commands "cifs disable" then "cifs enable" will allow to get back access to CIFS share. The share may be available for a while then it becomes unavailable at Windows client level after a while.    






If DNS is being used for name resolution, then ensure that the DataDomain Fully Qualified Domain Name (FQDN) used for the Data Domain hostname, and also the name used at CIFS config level, can be both resolved by the DNS server.
