> Hi all,
> I have been setting up a samba3 domain controller, all seems to work
> fins on the samba side, until i try to join a workstation to the domain.
>  From a windows XP client, the following happens...
> Enter computer properties, computer name tab... click Change...
> Enter "SUSSEXMC.COM" in the domain box, click ok
> Now is where things start going wrong..
> XP waits for a little while, before responding with:
> "A Domain Controller for the domain SUSSEXMC.COM could not be contacted"
> Clicking details reveals:
> "DNS was succesfully queried for the service location (SRV) resource
> record used to locate a domain controller for the domain: SUSSEXMC.COM
> The query was for the SRV record for _ldap._tcp.dc._msdcs.SUSSEXMC.COM
> The following domain controllers were identified by the query:
> smc1.sussexmc.com
> Common causes of this error include:
> - Host (A) records that map the name of the domain controller to its IP
> addresses are missing or contain incorrect addresses
> - Domain controllers registered in DNS are not connected to the network
> or are not running."
> Now ALL using the same XP client...
> I can verify that the A records are correct using nslookup (Server ip is
>, reported by DNS server at (Also the machine gets
> its IP address from DHCP on the same server, and this correctly updates
> the forward and reverse dns zones to reflect this))
> I can also verify the DC is running, as if i manually enter "\\smc1" or
> "\\smc1.sussexmc.com" into windows explorer (the first time) i am
> prompted for a username/password (and providing valid credntials allows
> me to logon and see the main shares on the PDC (sysvol, netlogon,
