This is a vague statement. BIND 9 supports Win2K at least as much as BIND 8
does. The only thing lacking is GSS-TSIG support, not that GSS-TSIG is RFC'ed
anyway...

My understanding was that this is a problem with older versions of Solaris,
not BIND _per_se_. You can, of course, always compile with threads disabled.
Again, how is this worse than BIND 8?

In general, why don't you read some of the documentation that comes with BIND
9? The feature list is changing with each release; I believe BIND 9.1.1 is
close to having all of the functionality of BIND 8 that it is intended to
have, plus of course lots of extra functionality.
In the interests of full disclosure, I should point out that I'm not running
BIND 9 in production yet. But that's mainly because we're somewhat paranoid
about stability issues here, and since I'm running older versions of Solaris
on most of my DNS boxes, I can't really reap the benefits of multi-threading
anyway...
I would, however, advise anyone with a normal risk tolerance and more
up-to-date OS platforms to migrate to BIND 9. If that recommendation seems
hypocritical, then so be it.
