NT Upgrade to Win2003 AD & Exchange 5.5

By Dennis.billstrom ·
Is it possible to Upgrade a NT 4.0 Domain to Win2003 AD and continue to run Exchange 5.5 on a NT 4.0 member server? Will the ADC make a connection to the Exch 5.5 directory? The 2003 AD will be in mixed mode.

I've been told that the Exchange Server has to be running on at least a Win 2000 member server, not a NT 4.0 machine.

Thanks for any help....
