I work for an Educational facility and have about 100 mac clients, they all are authenticating to AD, I can add them fine and they work great and then after a while they stop logging in, I have a lab that I just bound 2 months ago and 8 of the 20 macbooks will no longer log into AD. When I check the security log on the DC it has dozens of entries everytime anyone tries to login with an AD account on the MAC. All the research I have seen so far doesnt help me.

They are 10.6 clients connect to Server 2003. They are syncing time with my 2003 DC.
If I unbind rebind they work again for an unknown amount of time. Thanks for any help in advance.Art. What is the exact error that you have got? Try to unjoin and re-join a MAC computer to the domain and check the result.

I have unbound and rebound the Mac's several times that's why I'm posting, I'm tired of doing it I have 100 computers. After you rebind all is fine for a while maybe weeks maybe months I'm not sure, then all of a sudden for no reason they just stop login in to AD.
If you check the directory status on the MAC client all lights are green indicating all should be well. Below is the error that is logged when you try and login to AD from a Mac that is having problems.
Event Type: Failure Audit Event Source: Security Event Category: Account Logon Event ID: 675 SOURCE: SECURITY. EVENT ID: 675 Date: 4/26/2011 Time: 3:33:26 PM User: NT AUTHORITY SYSTEM Computer: S-HBHS1 Description: Pre-authentication failed: User Name: hb-a35-05$ User ID: HBHS-AD hb-a35-05$ Service Name: krbtgt/HBHS.HBUHSD.AD Pre-Authentication Type: 0x0 Failure Code: 0x18 Client Address: 10.74.114.33 Thanks Art. Do you have windows 2008 also in your domain, if yes, according to below article event id 675 is expected & can be ignored. I would suggest contact MAC for any hotfix released recently. Run dcdiag /v /c /d / e to analyze the health of your AD environment. It can't be sure there is problem with AD or Mac clients as both can be the problem. Event id 675 is related to authentication,so it might be possible possible if you don't have windows 2008 as DC, introducing it might resolve the issue.
There can be the issue with certificate too. Thanks for all the reponses, the account it's referring to is the machine account, not a user account. So you cant login as any network user when the machine account is 'locked out'. I can unbind from domain and rebind and then all is well.for a time and then magically a couple months down the road it happens again. We have no 2008 DC's in our domain, our district has a couple at their office but they are just member servers not DC's.
I've tried calling Apple and they say they cant halpe me because it's a windows server issue and for me to call microsoft. I call microsoft and they want me to pay a couple hundred dollars just to tell me they dont support mac clients.
