COMMAND

    open to guest access

SYSTEMS AFFECTED

    Win NT 3.5, 3.51, 4.0

PROBLEM

    This text had source ex NT pages by Bill Stout.

    Everyone has remote access to an NT systems' registry by default.

    NT 4.0 has a new registry key:

        <HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurePipeServers\Winreg>

    If this key does not  exist, remote access is not  restricted, and
    only  the  underlying  security  on  the  individual  keys control
    access.

SOLUTION

    Make a key (for 4.0) or upgrade your software (others).
