Joining Windows Domain With .local Dns Name



Wondering if you can help me, my company runs a windows 2003 domain with fairly high security.

The DNS Domain name has .local rather than .com, the hasn't been a problem with any of the PC's but when i come to join the Mac server to the windows domain it refuses to connect :(

I have read many instructions available on the internet and followed them but failed to connect. It fails to connect when trying to "bind" the Domain and Forest name. I have read somewhere that the Macs dont like the Domain to be called ".local" as the use "local" for other stuff.

Do you have any ideas or links to usefull sites please?
