MSExchange ADAccess errors 2105 and 2106

I have a Windows 2008 R2 with Exchange 2010.
I noticed that every 15 minutes or so, I receive the following errors on the event log:

---------------------------------------------------------------------------------------------------------------------------------------------
(AS WARNING)
Event ID 2106
Process STORE.EXE (PID=3384). Exchange Active Directory Provider failed to obtain DNS records for forest DC=mydomain,DC=com. DNS Priority and Weight for the Global Catalog servers in this forest will be set to the default values 0 (priority) and 100 (weight).  
---------------------------------------------------------------------------------------------------------------------------------------------
(AS WARNING)
Event ID 2105
Process STORE.EXE (PID=3384). Exchange Active Directory Provider failed to obtain DNS records for domain mydomain.com. DNS Priority and Weight for the Domain Controllers in this domain will be set to the default values 0 (priority) and 100 (weight).
---------------------------------------------------------------------------------------------------------------------------------------------

What can I do to know why this is happening and how to correct it?

Regards,
Roberto.

Make sure that the domain controllers for the domain specified in the event description are registered correctly on the DNS server

Also check with EXBPA and see with its warnings for the same and it will also tell you how to resolve them.

The EXBPA does not report any errors.
How do I make sure about the DNS registered correctly?

Thanks Rancy.

Is there a server in that evenet ID and hope there is no issues with Exchange connectivity to DNS and DC\GC ?

You can run DCDIAG for this and check.

1) There is no server on the EventID... I just replaced 'TECNICARD' with 'MYDOMAIN' when I posted the question originally.

2) I don't know why there is info about TECNICARD-MIAMI.... the domain is TECNICARD.COM... (maybe someone made a mistake when installing the first time?)

3) Can I go into and change those values to only TECNICARD or TECNICARD.COM ?


Here is the results of DCDIAG:

Check in DNS if you have any zones for TECNICARD-MIAMI ?

My best bet is that _msdcs.technicard.com and _msdcs under technicard.com is causing issues, you'll need to have one removed.

Read http://support.microsoft.com/kb/817470

It explains your scenario and list steps that would have a clean DNS, thereby helping you to solve Exchange mess.
