Hello,
We have suddenly started to experience mysteriously random
users, for no reason at all, accounts lockout. We have
about 1200 users and a couple a day lockout.

We are running AD on Windows 2000 with post sp3 patches.
It may have started after we went to sp3 but we can't say
this for certain.

Has anyone seen or experienced anything like this?

Thanks

Paul
