Active Directory Replication and DNS Problems
Hi there,
I've been having some nasty looking error logs for a while and it seems to be gradually getting worse.
Our current setup is as follows:
Two windows 2000 Advanced Server 2000 machine called - AD1 and AD2
These should be setup to replicate to and from each other.
Currently AD1 has the following error logs:
App Log:
Error SceCli 1202 repeated every 5mins
Security policies are propagated with warning. 0x4b8 : An extended error has occurred.
For best results in resolving this event, log on with a non-administrative account and search http://support.microsoft.com for "Troubleshooting Event 1202s".
Directory Service:
Error NTDS Replication 1084
Replication error: The directory replication agent (DRA) couldn't update object CN=D5334BA0F6094637B74D193 6F1151632, CN=VolumeT able,CN=Fi leLinks,CN =System,DC =xxxxx,DC= co,DC=uk (GUID 5dea3400-5113-45ec-8b5a-6e aa55b05ad9 ) on this system with changes which have been received from source server ced2d5b7-a279-450c-9c44-b3 7a4c3b8f03 ._msdcs.xx xxx.co.uk. An error occurred during the application of the changes to the directory database on this system.
The error message is:
The replication operation encountered a database error.
The directory will try to update the object later on the next replication cycle. Synchronization of this server with the source is effectively blocked until the update problem is corrected.
If this condition appears to be related to a resource shortage, please stop and restart this Windows Domain Controller.
If this condition is an internal error, a database error, or an object relationship or constraint error, manual intervention will be required to correct the database and allow the update to proceed. It is valuable to note that the problem is caused by the fact that the change on the remote system cannot be applied locally. Manually updating the objects on the local system in not recommended. Instead, on the source system (which has the changes already), try to reverse or back out the change. Then, on the next replication cycle, observe whether the change can now be applied locally.
The record data is the status code.
Error NTDS KCC 1014
The replication topology update task terminated abnormally with code e0010001.
Error NTDS KCC 1130
The automatic topology generator was unable to complete the topology for site CN=XXXXX,CN=Sites,CN=Confi guration,D C=XXXX,DC= co,DC=uk, error code 7, and internal id f08028f.
DNS Log:
Error DNS 4011
The DNS server was unable to add or write an update of domain name XXXXX in zone letts.co.uk to the Active Directory. Check that the Active Directory is functioning properly and add or update this domain name using the DNS console. The event data contains the error.
Error DNS 4015
The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The event data contains the error.
Error DNS 9999
The DNS server has encountered numerous run-time events. These are usually caused by the reception of bad or unexpected packets, or from problems with or excessive replication traffic. The data is the number of suppressed events encountered in the last 15 minute interval.
Error DNS 3000
The DNS server is logging numerous run-time events. For information about these events, see previous DNS Server event log entries. To prevent the DNS Server from clogging server logs, further logging of this event and other events with higher Event IDs will now be suppressed.
FRS:
Error NTFRS 13508
[1] FRS can not correctly resolve the DNS name ad2.co.uk from this computer.
[2] FRS is not running on ad2.co.uk.
[3] The topology information in the Active Directory for this replica has not yet replicated to all the Domain Controllers.
This event log message will appear once per connection, After the problem is fixed you will see another event log message indicating that the connection has been established.
AD2 has the following:
App Log:
SceCli 1202
ESENT 454
Directory Service:
Error NTDS ISAM 701
FRS:
Error NTFRS 13568
I've also noticed the following AD 1, under Local Security Settings it displays: Windows Cannot open the local policy database. An unknown error occurred when attempting to open the database.
AND on AD2 under the same setting it says:
Windows cannot open the local policy database.Access to database has been denied.
So far I've tried to flush the DNS etc but no joy.
Any pointers where I should start looking?
Thanks in advance,
Craig

I'll keep refreshing the Event Viewer and see if it's helped.

OK Checked the logs this morning and the DNS errors seem to have cleared on AD1 - however I'm still getting the following:
AD1 -
FRS Error 13508
The File Replication Service is having trouble enabling replication from AD2 to LETTSAD1 for c:\winnt\sysvol\domain using the DNS name ad2.xxxx.co.uk. FRS will keep retrying.
Following are some of the reasons you would see this warning.
[1] FRS can not correctly resolve the DNS name ad2.xxxx.co.uk from this computer.
[2] FRS is not running on ad2.xxxx.co.uk.
[3] The topology information in the Active Directory for this replica has not yet replicated to all the Domain Controllers.
This event log message will appear once per connection, After the problem is fixed you will see another event log message indicating that the connection has been established.
I can PING the AD2 server using Name and IP from AD1 and I've checked the FRS on both machines and it seems to be running.
I'm also getting Error 1202 every 5 mins on AD1
Security policies are propagated with warning. 0x4b8 : An extended error has occurred.

On AD2 I'm still getting the following errors:

Error 439

Error 427
services (372) The database engine could not access the file called C:\WINNT\Security\tmp.edb.
All the DNS errors on both servers now seemed to be cleared, so thanks very much for that help.
I'm still getting the problem with the Windows cannot open the local policy database.Access to database has been denied.

Did you verify that time is synchronized properly?
ASKER
Hi there,
Yes the times are exactly the same.

Your DNS is still questionable. AD1 should point to itself. AD2 should point to AD1. (or the other way around. As long as the same DNS server is the primary for both DC's). Is that the way it is setup?
Also do you have multiple NICs on the DC's?
Also do you have multiple NICs on the DC's?
ASKER
Yeah I've got AD1 pointing to itself and AD2 points to AD1, single NIC on both.
Still getting the above errors on AD1 though. AD2 seems to be a lot better but still getting replication probs.

ASKER CERTIFIED SOLUTION

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Run a DCDiag on both your DC's and look for errors.
Run a NetDiag on both your DC's and look for errors.
Make AD1 point to itself for DNS in its TCP/IP properties
Make AD2 point to AD1 for DNS in its TCP/IP properties
Make sure the DHCP Client service is running on both DCs (this service is responsible for registering the SRV records).
Do an IPCONFIG /REGISTERDNS from the command line.
Now restart the Netlogon service on both machines one at a time. This will cause the DCs to register their DNS SRV records.
