[Samba] Windows 7 Can't Join Samba 3.5.4 PDC
Hi all,
When trying to join a windows 7 box to a samba 3.5.4 acting as a PDC I
am getting an error on the windows 7 box that says
DNS_ERROR_NO_DNS_SERVERS (the full error log is included at bottom of
mail). WinXP machines are able to join the domain fine, just not
windows 7 boxes. My (sanitized) config is located is included at the
bottom of the mail.
I have tried doing the registry patches to the windows 7 box but am
not using those right now. The error persists even with the registry
changes applied.
Can anybody tell me what I need to do to fix this error?

The domain name "RMC2" 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.
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 "RMC2".
The error was: "No DNS servers configured for local system."
(error code 0x0000267C DNS_ERROR_NO_DNS_SERVERS)
The query was for the SRV record for _ldap._tcp.dc._msdcs.RMC2
Thanks,

Ideally you would have the following workgroup= DOMAINNAME server string = SERVERNAME netbios name = SERVERNAME And you should have a DNS " A"entry for "servername." On the samba wiki there are two sets of registry changes. For Samba 3.5.x you should only need one set- ie. the following HKLM\System\CCS\Services\LanmanWorkstation\Parameters DWORD DomainCompatibilityMode = 1 DWORD DNSNameResolutionRequired = 0 Is your client configured to use the PDC as its WINS server (this can be assigned via DHCP.) That should help it find the server. Otherwise it may assume that the domain it is looking for is an Active Directory domain- thus the DNS query looking for the non-existent "ldap" active directory server.
