Different domains (from different forests) don't sync between them. Pass through authentication works if trusts exists. Windows 2000 uses kerberos but soports NTLM (used in NT4 domains). Now for Exchange, you would use the ADC during migration phase to Exchange 2000... if you're not migrating you don't need to use it.

Mixed mode supports NT4 BDCs, native mode doesn't. Native mode has new functionality enabled specially related with administration (you can now nest groups for example). All your workstations and trusts will keep on working fine!

There are no NT servers in the 2k domain. If I were to change the 2K domain to Native Mode, will the trust still work?
