DNS Problem

Hi,

I have 2 DC in my network, primary server is giving problems accessing internet. I am not using Proxy, for internet I am directly connected to my firewall (Cisco PIX 515) n through switch it is distributed to my workstations.

Now from our whole network we are not able to access internet, we can access yahoo messanger but not any other things.

I tried using IP address and I found that I can access but not through URL. I came to know its DNS Problem.

DCDiag , Netdiag results are here.

DC Diagnosis

Performing initial setup:
   * Verifing that the local machine dtt-bar-dc-01, is a DC.
   * Connecting to directory service on server dtt-bar-dc-01.
   * Collecting site info.
   * Identifying all servers.
   * Found 4 DC(s). Testing 1 of them.
   Done gathering initial info.

Doing initial non skippeable tests

   Testing server: Default-First-Site\DTT-BAR-DC-01
      Starting test: Connectivity
         * Active Directory LDAP Services Check
         DTT-BAR-DC-01's server GUID DNS name could not be resolved to an
         IP address.  Check the DNS server, DHCP, server name, etc
         Although the Guid DNS name
         (fd26e331-3348-4990-8496-53cd401e0f9f._msdcs.dttindia.local) couldn't
         be resolved, the server name (dtt-bar-dc-01.dttindia.local) resolved
         to the IP address (10.169.116.10) and was pingable.  Check that the IP
         address is registered correctly with the DNS server.
         ......................... DTT-BAR-DC-01 failed test Connectivity

Doing primary tests

   Testing server: Default-First-Site\DTT-BAR-DC-01

Do you have forwarders configured on your DNS servers?
Point the forwarder to your ISP's DNS servers.

hello friends,

I m back with solution of my own question.

The alternate DNS name was creating problems for the preferred DNS server so i removed it from the DNS Config. and now the problem is solved.

Thanks for the support.

Best regards,
