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
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
(fd26e331-3348-4990-8496-5
be resolved, the server name (dtt-bar-dc-01.dttindia.lo
to the IP address (10.169.116.10) and was pingable. Check that the IP
address is registered correctly with the DNS server.

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.
