[Samba] Intermittent authentication error

I have an intermittent authentication error between a Windows 2003 Server and AIX 6.1 TL4 Samba 2.2.7. I have the Samba server passing auth details to an active directory server. The account exists on AIX but is locked and there is no smbpasswd entry (this is how I setup all my samba shares). On the Windows server a mapping has been created to mount this path on restart. In most cases this works fine but from time to time it fails with authentication issue. Rebooting the Windows server fixes the problem but I would like to find the root cause and fix it. I have setup debug level 2 and got the following. Any help would be greatly appreciated.
  Couldn't find user 'aonunitp' in passdb.
  Rejecting user 'aonunitp': authentication failed
  Couldn't find user 'aonunitp' in passdb.
  NT Password did not match for user 'aonunitp'!
  Defaulting to Lanman password for aonunitp
