Legato Cluster has supported NT4/W2K since 1998. Latest version does registry update monitoring. I've done this in an Active-Active mode, but it doesn take some careful thought in architecting the data patterns, might not be for the faint-at-heart.

If you want a "free clustering service", if you consider buying another machine and MS license Free, with a Active-Passive type implementation go with MSCS.

So MSCS does not support active-active clustering with shared storage and shared IP? The docs I've skimmed aren't particularly clear on this point. I do remember playing with a load balancing feature within W2K which would seem to work very well for a farm of IIS servers, all sharing content from a common filesystem on a Netapp. Probably won't work for SQL or Exchange though.

http://www.integratus.com/ are a good place to start.

This looks interesting... Solaris, Linux and FreeBSD support (which is the bulk of the servers we run), but no NT/2K yet, unfortunately. Thanks for the pointer.
