hi,

introduce my current environment：

FAS3220 , VERSION: NetApp Release 8.1.3P3 7-Mode.

the problem:

the prior environment, we created a cifs share with two windows 2008 R2 active directory.

according to the customer request, I was created two new windows 2008 R2 host. and adding to active directory

but the from the netapp GUI interface , for domain controler display , i can see three active directory. it's not four

active directroy

from the command line, check the domain info:

but after about ten minutes , will be show the following picture, at the domain directory item, all of the active directory is disappear. during the cifs service is unavailable also.

so what's wrong for the NETAPP storage ?

With the old versions involved my first suspect is that SMB1 been disabled on the DC

For more troubleshooting. You'll have to provide some "messages" logs output (preferably "options cifs.trace_dc_connection on" been enabled and another domain join been attempted").

Note that 7mode system can discover all DCs but only connect to 3 DC at the same time.
