Child domain in existing tree

I have a windows 2000 domain with Active directory installed. The domain (rites.com) is installed in Location A. Recently I installed a new child domain (sales.rites.com) in the existing tree at a new Location B. Both the locations are separated by a WAN link (T1). I have created an IPSEC tunnel between the two offices for connectivity. While installing the child domain I created the first DC (A1WSITE2-1) as a child domain to the existing root domain rites.com. Right now the DC (A1WSITE1-2) is pointing to the DNS from the root domain (both preferred and secondary). Do I need to install a local DNS server in location B for sales.rites.com? Can I point all my servers to the DNS server in the root domain? Is it a recommended setting.

Thanks

The best recommendation is to have a least one DNS server & DC in every single location.
Why ? simple...what if somehow SiteA lost connection with SiteB ? How are clients from SiteB going to get DNS responses from a DNS server they cannot reach ?
The best thing is to define a DNS server in your SiteB, as a secondary zone...so It will replicate all the entries from your root domain....and don't forget to point your SiteB's computers to have your SiteB DNS Server as their primary DNS ;-)
You'll also reduce traffic for DNS queries between SiteA and SiteB, and you'll have a complete DNS fault tolerance Site.
Hope it helps !!
