Are the times synced up between filer and the domain controllers? Kerberos is very time sensitive.

Today I had several filers at different OS levels stop serving data via CIFS with the following errors. I had to stop and restart CIFS to get CIFS working properly. The filer acted as if its kerberos ticket wasn't valid with any of the domain controllers. Has anyone seen this before?
Cifs domain info command:
Not currently connected to any DCs Preferred Addresses: None Favored Addresses: ip WNTNABO2 PDCBROKEN ip WNTNABO1 PDCBROKEN Other Addresses: ip WNTNABO4 PDCBROKEN ip WNTNACRUBO1 PDCBROKEN
/etc/messages output:

Any insight into this would really help me out. I have a case open with Netapp as well.
