Product Line
Resetting IUSR_Millennium password – IUSR account locked out
If you'll change the IUSR_Millennium password it must me done in several places in IIS Manager: local users, IIS default website, Mill drive website, IIS server level, and both applications pools but...I think the locked out issue... is not related to the password/authentication...
try resetting the password...
If there are additional queue boxes, the same - IUSR_Millennium must be updated on those boxes as well
If IUSR_Millennium account is locked out, it may mean password is not matching at all sites as per above.
