Is there a good technical document out there the details how Exchange 2010 works with Active directory. What requirements 2010 has on AD. We implemented Exch 2010 with a mix of AD 2003 and 2008 and have had a few issues with slowness. A consulting is telling us that we may not be to spec with AD... Thanks jwilmer

For example you will need an AD with Global Catalog role on each site where you have an exchange mailbox server etc. Also you may want to download and read the IPG for exchange 2010.
