Just in case this happens to someone else, MS KB Q285903 fixed the problem.

>Hello,
>
>I recently installed a new hard drive on my WIN2000 Svr, SP2. The drive works great, but ever since I installed it, I keep getting errors in the Application Log. First, I get a warning that reads:
>
>"Security policies are propagated with warning. 0x534 : No mapping between account names and security IDs was done."
>
>Next, I get an error that reads:
>
>"The Group Policy client-side extension Security was passed flags (17) and returned a failure status code of (1332)."
>
>I have no idea why these warnings and errors are occurring, or how to fix them. Everything appears to be working OK, but these warnings and errors keep coming --- sometimes every minute and sometimes every five minutes. My log continues to fill up.
>
>Any help in resolving this issue will be appreciated.

>Thanks,
