Dear All, I have a Virtual Box Where Windows Server 2008 r2 is installed.Virtual box is hosted by a machine which Uses Windows Server 2008 r2. Host machine is a domain controller.I have added guest to another domain other than host.But whenever I tried to add guest machine to host domain It shows me following error(See below). An 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 "crmrc.com". The error was: "No records found for given DNS query." (error code 0x0000251D DNS_INFO_NO_RECORDS) The query was for the SRV record for _ldap._tcp.dc._msdcs.crmrc.com Could you please suggest me the solution for it? Thanks and Regards, Yusuf
