Windows XP Clients in W2k3 AD Domain Sign on to a DC in the wrong domain

[mb29990]

Any help would be greatly apriciated on this.
We have a Windows 2003 Active Directory domain. I am located at the UK head quaters which acts as a hub for remote sites including our US head quaters. We have a site in the UK that has a local Domain Controller. But some of the clients wont use it. But the wierd thing is that many of them skip the DCs at the UK HQ and go straight to a DC in the US.

Anyone got any ideas why this would happen. the DC is fully registered in DNS and is it's self a DNS server that the local clients are useing.

what operating system are the clients running? the client pcs are members of the a/d domain, right?

do you have your subnets assigned to the correct sites in active directory sites & services?

did you create your domain controllers locally and then ship them to the remote locations, or did you promote the servers after they were located at their sites?
