What’s the alternative?

What is your need ? DNS ? Auth ? File sharing ? Print sharing ? GPO ? Remote control ? SSO ? Authentication or authorization ?

		Wow, NetInfo. What a blast from the past. To be clear NetInfo is not an alternative. It's just not generic enough and not really a good fit for Windows. NetInfo is too much a Unix solution, so there's no cross-realm/domain "forest" functionality, no support for SIDs, etc.
