Linux DHCP/DNS Server with Active Directory

I have several branch offices with nearly redundant Windows 2003 servers - they are currently used for DHCP/DNS and a couple of shares for software distribution which are not required by the clients at the branch. To save on licence fees I plan to replace these with Linux servers.

I have configured DHCP, DNS (configured to forward to central Windows DNS servers) and Samba and everything appears to be OK but I was just a little concerned about the use of the Linux DNS server with Active Directory. Will my Windows DNS servers be updated with hostname records etc when clients obtain a DHCP address from the Linux DHCP server? Is there anything else I should be aware of? Or I am best just pointing my clients to the Windows DNS servers across the WAN?

Pointing your clients would work if you have a high speed WAN link between your sites but it would unnecessarily route too many packets.
I assume you are using BIND for your DNS config.
If so use this URL to check your config
