all functionalitly of 2003 is available in LH, if you wanted to ADD a LH server to your domain, you could make it a DC and replicate AD to it without issue ***NOTE*** LH is still beta, please do not do this with your production environment!!! build a test environment and add LH server to see how they operate and react to your environment configurations. Thanks but how do i replicate everything in AD 2003 to LH? without doing all accounst and groups individually? thanks
