The following CR has been filed:

6941787 Spuriuos message "DC discovery failed" upon refresh.

I've reproduced this in-house. My understanding is that CIFS server has successfully located a domain controller and the above message is spurious. BTW, your CIFS server wasn't restarting but some changes in the configuration that might have triggered it to refresh.

Not every 5 minutes. I haven't added any shares for several days now.

This one spans this period:

[ Apr  5 23:29:43 Rereading configuration. ]

[ Apr  5 23:29:44 Executing refresh method (:kill). ]

smbd: DC discovery failed

[ Apr  5 23:34:44 Rereading configuration. ]

[ Apr  5 23:34:44 Executing refresh method (:kill). ]

smbd: DC discovery failed
