Notes

• It has been reported that some customers who have installed the final, released version of the Windows NT 4.0 Option Pack over a beta version have had to remove and reinstall the released version.
• IIS uses Windows NT Challenge Response as one of its security authentication options. For IIS to install correctly, the NT LM Security Support Provider service must be installed and running. If it is not, the Windows NT 4.0 Option Pack Setup program may fail.
