What are the options for places like ours that are still mostly running
Windows NT4 sp6a? The zfdagent with zenworks suite 6.5 is not
installing onto my test NT machine, says it isn't a supported OS. I
also see that in the docs, it has been tested with w2k, xp, 98se. But I
don't see any mention of it actually not working with NT.

I was initially going to set up the new client update to remove the nal
stuff from the client install after having run the agent install (moving
from 4.83 clients to 4.9)

I see that the zfd4 supports NT, why doesn't 6.5? Can I go ahead and
install the zfd4 agent on the NT machines? will it cause any issues?
