Filer unable to authenticate to Active Directory

[davisr651]

i have 2 filers clusterd w/ontap3.3.1

for some reason, one of the files is unable to authenticate with our Active directory domain.. the following error occurs.. unable to acquire credentials: invalid password: no logon servers available.  nobody is able to access the cifs share either...

I did the following to try to resolve the issue..

pulled the file out of our AD domain, and readded it

no errors with  DNS,

restarted CIFS reset it too.

rebooted the filer

can you help me out?

have you verify that the date between the filler and your active directory server have less than 5 min difference ?
