An Active Directory Domain Controller for This Domain Could Not be Contacted with windows 7 laptop

I have server running Zentyal. And I have a problem with joining my domain. The problem exists with only my laptop. I've tried some other PC's and they successfully join the domain.

All the machines that I used run windows 7.

I tried to ping the domain controller from my laptop and it was successful. I also tried the other way around and that was also successful.

When I search Google I found some "fixes" that should work but they did not work for me.

1. I changed my dns server aadress to my domain controller.



2. I set my default gateway to domain controller ip but sill nothing.

Here's the error message that I get when I try to join the domain:

The domain name "KK" might be a NetBIOS domain name. If this is the
case, verify that the domain name is properly registered with WINS.

If you are certain that the name is not a NetBIOS domain name, then

the following information can help you troubleshoot your DNS
configuration.

The following error occurred when DNS was queried for the service
location (SRV) resource record used to locate an Active Directory
Domain Controller (AD DC) for domain "KK":

The error was: "DNS name does not exist." (error code 0x0000232B
RCODE_NAME_ERROR)
