I am experiencing an issue with my filer since we have migrated our DC to windows 2008 R2.
Users cannot access the Cifs shares due to an authentication issue.
In the filer the following message is logged auth.dc.NoDCConnection:error]: AUTH: Unable to connect to any Domain Controller for the domname Use 'cifs domaininfo' for a listing of DCs tried.

When I run cifs domaininfo all the DC are shown as pdcbroken
Do you have any idea on how to fix this issue. is there any consideration to take with windows 2008R2

thanks for your help.
