I followed up on tip about KB article Q814770 (not a public article). Do a google search on Q814770 and you will get two threads on microsoft.public.win2000.general.
Those threads suggested I call Microsoft Support, which I did. 1.800.936.4900. In the call I referenced Q814770 and 329170. No charge for the help. They gave me a case number and emailed a link for a fix, which I've downloaded but not yet installed. I was hoping the download would include a copy of Q814770 so I could confirm that the fix covered my situation, but the article was not included. So I called Microsoft again, and they emailed me a copy of Q814770. The following are excerpts from this article:

Because I can tolerate the workaround, I'm inclined not to risk this additional "fix" and just wait for SP 4.
