Over the weekend we had a complete power down for work being carried out on the mains power supply.  On booting the system this morning I get the following errors on my PDC before the secondary has been booted up.

Event Type:      Error
Event Source:      NTDS Replication
Event Category:      Replication
Event ID:      1863
User:            NT AUTHORITY\ANONYMOUS LOGON
Computer:      DC1
Description:
This is the replication status for the following directory partition on the local domain controller.
 
Directory partition:
DC=Domain,DC=local
 
The local domain controller has not received replication information from a number of domain controllers within the configured latency interval.
 
Latency Interval (Hours):
24
Number of domain controllers in all sites:
1
Number of domain controllers in this site:
1
 
The latency interval can be modified with the following registry key.
 
Registry Key:  
HKLM\System\CurrentControlSet\Services\NTDS\Parameters\Replicator latency error interval (hours)
 
To identify the domain controllers by name, install the support tools included on the installation  CD and run dcdiag.exe.  You can also use the support tool repadmin.exe to display the replication latencies of the domain controllers in the forest.   The command is "repadmin /showvector /latency <partition-dn>".

Event Type:      Warning
Event Source:      NTDS Replication
Event Category:      Replication
Event ID:      2092
User:            NT AUTHORITY\ANONYMOUS LOGON
Computer:      DC1
Description:

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.
 
FSMO Role: CN=,CN=,DC=Domain,DC=local
 
User Action:
 
1. Initial synchronization is the first early replications done by a system as it is starting. A failure to initially synchronize may explain why a FSMO role cannot be validated. This process is explained in KB article 305476.
2. This server has one or more replication partners, and replication is failing for all of these partners. Use the command repadmin /showrepl to display the replication errors.  Correct the error in question. For example there maybe problems with IP connectivity, DNS name resolution, or security authentication that are preventing successful replication.
3. In the rare event that all replication partners being down is an expected occurance, perhaps because of maintenance or a disaster recovery, you can force the role to be validated. This can be done by using NTDSUTIL.EXE to seize the role to the same server. This may be done using the steps provided in KB articles 255504 and 324801 on http://support.microsoft.com.
 
The following operations may be impacted:
Schema: You will no longer be able to modify the schema for this forest.
Domain Naming: You will no longer be able to add or remove domains from this forest.
PDC: You will no longer be able to perform primary domain controller operations, such as Group Policy updates and password resets for non-Active Directory accounts.
RID: You will not be able to allocation new security identifiers for new user accounts, computer accounts or security groups.
Infrastructure: Cross-domain name references, such as universal group memberships, will not be updated properly if their target object is moved or renamed.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

This is happening for all FSMO Roles.

Everything seem to sort itself out once DC2 has been started.  Do I need to worry about this ?

No need to worry - this is a replication message for AD, and obviously until the second dc is started, it cannot replicate;
(the dc's replicate the AD schema between themselves so that all AD info is up to date on all of them in case one fails)

Thanks thought that would be the case but just need to confirm.
