Long boot time W2K8 R2
two DC's with DNS services pointing on each other as primary DNS and on self as alternative DNS
Problem: DC takes like 5+ min to apply settings on starts if second DC is down
tried to set primary DNS on itself and alternative on DC which is turned off - still takes long time to boot.
event logs at the time of admission
ID 1014 Name resolution for the name _ldap._tcp.dc._msdcs.mydomain.com timed out after none of the configured DNS servers responded. ID 4012 The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed ....... ID 1202 This computer is now hosting the specified directory instance, but Active Directory Web Services could not service it. Active Directory Web Services will retry this operation periodically. ID 14550 The DFS Namespace service could not initialize cross forest trust information on this domain controller, but it will periodically retry the operation. The return code is in the record data. ID 6005 The winlogon notification subscriber <GPClient> is taking long time to handle the notification event (CreateSession). ID 1012 Name resolution for the name mydomain.com timed out after none of the configured DNS servers responded. ID 2092 This server is the owner of the following FSMO role, but does not consider it valid. For the partition which contains the FSMO, this server has not replicated successfully with any of its partners since this server has been restarted. Replication errors are preventing validation of this role. Operations which require contacting a FSMO operation master will fail until this condition is corrected. ID 14550 The DFS Namespace service could not initialize cross forest trust information on this domain controller, but it will periodically retry the operation. The return code is in the record data. ID 14550 The DFS Namespace service could not initialize cross forest trust information on this domain controller, but it will periodically retry the operation. The return code is in the record data. ID 10 Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected. ID1202 The DFS Replication service failed to contact domain controller to access configuration information. Replication is stopped. The service will try again during the next configuration polling cycle, which will occur in 60 minutes. This event can be caused by TCP/IP connectivity, firewall, Active Directory Domain Services, or DNS issues. ID 2087 Active Directory Domain Services could not resolve the following DNS host name of the source domain controller to an IP address. This error prevents additions, deletions and changes in Active Directory Domain Services from replicating between one or more domain controllers in the forest .......
As I understood this is normal http://support.microsoft.com/kb/945765/en-us
but who can tell me in detail what is happening on startup and what causes this conflict
On 2 running DC's boot takes ±30sec + few simple logs
