oddities to resolve in my netlogon.log

Good Afternoon. I am running netlogon logging on one of my domain controllers to troubleshoot some issues I am having with 5719 errors on my clients(servers).
here is my setup:
3 DCs
DC1 - PDC role 2008 server
DC2 2003 server R2 enterprise (CA)
DC3 2003 server R2

so I am looking at the log on DC2 and this is what I see that concerns me... (in BOLD)

here is what I know/what I have done so far:
ping dc1 dc2 and dc3 all are good... all resolve and ping using netbios and fqdn
ping -a dc1 dc2 dc3 all resolve ping by IP address
nltest /dsgetdc:mydomain.com run on dc2 returns:
           DC: \\dc2.mydomain.com
      Address: \\192.168.104.20
     Dom Guid: 8cac2fde-c52c-4e54-93a6-5510b4b61476
     Dom Name: mydomain.com
Forest Name: mydomain.com
Dc Site Name: Default-First-Site-Name
Our Site Name: Default-First-Site-Name
        Flags: DS LDAP KDC TIMESERV GTIMESERV WRITABLE DNS_DC DNS_DOMAIN DNS_FOR
EST CLOSE_SITE
The command completed successfully

other nltest queries look good as well. trust, secure channel - all that.

I just can't figure out what is happening here. why the ping errors that we don't host the named domain - yet we DO host the domain and it IS pingable?
Why the 1355 errors (which I think means domain doesn't exist)? It seems to be querying for the domain dc2.mydomain.com - but my domain name is mydomain.com - why is is querying for the domain controller? I thought it might be looking for the PDC but that is dc1.mydomain.com and it doesn't like that one either!

Now netlogon is working ok and processing requests correctly for the moment. I think my 5719 is related to network communication - but I keep seeing these other errors and want to get them worked out as well.

I normally google until my fingers fall off looking for answers but google has been very little help with this issue so any direction you can give will be helpful.

Thanks in advance...

Howdie!

What does the DNS configuration on DC2 look like? Can you use nslookup and target it to use DC2 as the server for resolving queries? Can you resolve the domain as well as the fully qualified domain names of all DCs?

A client doesn't look for the PDC for authentication/logon. It actually looks at what site it is in and queries DNS for DCs in the same site. It would then ask any random DC (given there is no priority set in DNS and they are in the same site) for authentication.

What does the DNS configuration on DC2 look like?

The DNS on DC2 is this:
primary: pointing to itself
secondary: pointing to DC3

My DC2 has two NICS but one of them is unregistered/never registered in DNS using KB292822 -Not ideal for a DNS on a DC - but necessary until I can get some more boxes.

Can you use nslookup and target it to use DC2 as the server for resolving queries? Can you resolve the domain as well as the fully qualified domain names of all DCs?

using nslookup server=dc2:
query - result

mydomain.com - 192.168.104.20 192.168.104.21 192.168.100.74 (we have two sites - DC2 is in the 104 subnet site - DC3 is in 100 site)

dc1.mydomain.com - 192.168.104.21
dc2.mydomain.com - 192.168.104.20
dc3.mydomain.com - 192.168.100.74

site1 = dc1 and dc2
site2 = dc3

replication is working properly - although it is slow.

Any clues you can provide are appreciated. I can feel my hair turning gray trying to ferret out these issues!

Here is the connection info from netlogon.log gathered after restarting the netlogon service... I am pretty sure it is connecting properly:

Hi,

This issue may occur if you use a 1-GB network adapter and the Netlogon service starts before the network is ready. Please try to refer to the suggestions in the following article or just ignore this error if there is no other errors.

Event ID 5719 is logged when you start a computer on a domain, and the computer is running Windows Server 2003, Windows XP, or Windows 2000
http://support.microsoft.com/kb/938449

This issue may also occur because link status fluctuates as the network adapter (also known as the network interface card, or NIC) driver initializes and as the network adapter hardware negotiates a link with the network infrastructure. The Group Policy application stack executes before the negotiation process is completed and can fail because of the absence of a valid link.

Cannot connect to domain controller and cannot apply Group Policy with Gigabit Ethernet devices
http://support.microsoft.com/default.aspx?scid=kb;EN-US;326152

Try the following suggestions to disable Media Sensing to test.

How to disable the Media Sensing feature for TCP/IP in Windows
http://support.microsoft.com/kb/239924/

If the issue persists, please help to collect MPS Report on problematic computers for troubleshooting.

A. Download MPS Reporting Tool (MPSRPT_PFE.EXE) from the following link:
(http://www.microsoft.com/downloads/details.aspx?FamilyID=00ad0eac-720f-4441-9ef6-ea9f657b5c2f&DisplayLang=en)

Please note: The link may be truncated when you read the E-mail. Be sure to include all text between '(' and ')' when navigating to the download location.

B . Right click MPSRPT_PFE.EXE and select Run as Administrator to run this tool, and you will see a Command Window start up.

C . Please type Y with the message of <Include the MSINFO32 report? (defaults to Y in 15 seconds)[Y,N]?

D . When the tool is done you will see an Explorer Window opening up the %systemroot%\MPSReports\Setup\Reports\cab folder and containing a <Computername>MPSReports.cab file. After collecting, please use Windows Live SkyDrive (http://www.skydrive.live.com/) to upload the file and then give me the download address.

Thanks.

Howdie!

I'm sorry for asking a stupid question but - is that only happening on machine restart (DC2)? If so, can you switch the two DNS servers in the DC's network config (primary: DC3, secondary: Dc2)?

Cheers,

No, the 5719 error is happening on my clients long after the boot/restart. I am aware that I may get the 5719 error on restart.
And the 5719 is happening on a client machine. This is the netlogon.log from my domain controller.
I am trying to troubleshoot why I am getting the 5719. It points to some kind of communication problem and my first thought was DNS problems. That is why I am concerned when I see these errors in the netlogon.log on the domain controller:

03/30 17:01:10 [CRITICAL] Ping from DC2 for domain DC1.mydomain.com (null) for (null) on <Local> is invalid since we don't host the named domain.

03/30 17:01:10 [CRITICAL] NetpDcGetNameIp: DC1.mydomain.com: No data returned from DnsQuery.

03/30 17:01:10 [MISC] MYDOMAIN: DsGetDcName function returns 1355: Dom:DC1.mydomain.com Acct:(null) Flags: WRITABLE LDAPONLY DNS RET_DNS

I will look at the suggestions from Marvyn and see if he can help any. These errors just seem extremely odd and happen all day long - not just when I restart the machine or restart the netlogon service.
I would think that they are flagged CRITICAL for a reason? I feel like I have jumped through every hoop except tearing down my entire DNS/DC infrastructure to get these to go away. Although I am sure there are always other things to try and I am open to other ideas as well!

Hi,

I have the same problem on my 2008 R2 DC. Did you manage to find a solution?

This is very old thread, my suggestion is just raise your own thread with the necessary details of the issue and the environment.

Thanks for understanding.
