A. Service Pack 4 adds support for multiple domain controllers for a single domain to be configured in the LMHOSTS file (located in %systemroot%\system32\drivers\etc). Normally when a computer starts, the WINS server is queried for any \[1C\] entries, domain controllers, and it will return a list. This list is not geographically aware and you could be given a domain controller on the other side of the world.
An alternative is to specify a list of domain controllers in the LMHOSTS file (which is now checked before WINS is #PRE is in the entry) and have different LMHOSTS files in different regions.
Example entries in the file would be
18.104.22.168 titanic #PRE #DOM:SAVILLTECH
22.214.171.124 cuttysark #PRE #DOM:SAVILLTECH
