SYMPTOMS
On a Windows NT 4.0-based computer with the System Key (Syskey.exe) functionality enabled, the computer may stop responding (hang) before the logon screen is displayed. This problem may occur after you uninstall certain hotfixes or the Windows NT 4.0 post-Service Pack 6a (SP6a) Security Rollup Package (SRP).
CAUSE
This issue occurs if the Samsrv.dll or Lsasrv.dll file (or both) was removed. These files need to remain installed on the computer.
