AD fails to authenticate some computer accounts

I have a problem where our AD randomly fails to authenticate some computer
accounts. When the user attempts to logon to their system and a domain
controller is available they are given an error message, when I check the
event logs on the DC the following error is logged: Source NETLOGON Event ID:
5805
The session setup from the computer Computername failed to authenticate. The
following error occurred:
Access is denied.
Also I get an Event ID 5723
The session setup from computer 'computer name' failed because the security
database does not contain a trust account 'computername$' referenced by the
specified computer.

When I remove the computers from the domain and rejoin the problem goes
away. Why would the AD suddenly not recognize a computer account? This
happens pretty frequently and the only fix seems to be to rejoin the domain.
Is there some security setting that could cause this?

Re: AD fails to authenticate some computer accounts

Are these always the same computers that experience this?

If so it might be that the computer accounts themselves are corrupt. You can
test by removing the computer from the domain, delete the computer account,
then add the computer back to the domain and let the computer account be
recreated.

Re: AD fails to authenticate some computer accounts

I need some help. I am having the exact same issue but I con not re-join the server back into AD. I am seeing access denied errors no matter what account I use to join the machine into the domain.

I read a KB on MS that stated there was a patch for this but it was only on w2k, and that w2k3 sp1 fixed the issue. I am using 2wk3 sp2 ...

I have tried the NETDOM and other support tools with our any effect. Any other ideas ?
