DirectAccess clients DNS resolving issue

Hallo,

I am configured da. Then I go to DA server components monitor I see

green icons near: Teredo Relay, Teredo server, Isatap, DNS server.

Then I checked my client configuration with:

netsh namespace show effectivepolicy

I see result: 

DNS Effective Name Resolution Policy Table Settings

Settings for .mydomain.lt
----------------------------------------------------------------------
Certification authority                : DC=lt, DC=mydomain, CN=mydomain-ROOTCA
DNSSEC (Validation)                  : disabled
IPsec settings                           : disabled
DirectAccess (DNS Servers)       : 2002:xxxx:xxxx:1:0:5efe:172.30.16.xxx
                                                          2002:xxxx:xxxx:1:0:5efe:172.30.16.xxx
DirectAccess (Proxy Settings)           : Bypass proxy
Settings for crl.mydomain.lt

.....

Then I trying to ping DNS servers with 2002:xxxx:xxxx:1:0:5efe:172.30.16.xxx, 2002:xxxx:xxxx:1:0:5efe:172.30.16.xxx. Ping OK.

After this I ping two external IPv4 adresses of my DirectAccess server and Ping OK too.

Then I tryining to ping fqdns of my DA server and dns server I getting "Ping request could not find host DA".

I tryed to check Teredo connectivity Link: http://technet.microsoft.com/en-us/library/ee844188(WS.10).aspx and I see problem then

run command: From the netsh advfirewall prompt, run the set store gpo=”DomainName\DirectAccess Policy-{3491980e-ef3c-4ed3-b176-a4420a810f12}” command. I see result "Unable to contacts the specified domain. Make sure that the domain is valid and accesible, and then try your request again"

Please help me resolve this problems
