We are using SBS 2008 (primary DC) and Server 2008 (backup DC) with about 20 XP and W7 clients. Yesterday morning all clients encountered login problems (5805 NETLOGON: The session setup from the computer [DOMAINCOMPUTER] failed to authenticate. The following error occurred: Access denied).
We reintegrated all clients into the domain (put into workgroup, reboot, put into domain, reboot). Login with severals accounts o all clients was successful, but after about 30 minutes the problem reappeared for new logins with:
1. 5723 NETLOGON: Session could not be created ... followed by
2. 5805 NETLOGON: The session setup ... (see above).
What can cause these problems? All clients are listed in the AD.
