  Q266794 Windows 2000 SNMP Registry Entries Are Saved in Plain Text Format and
  Are Readable

SYMPTOMS
========

Microsoft has released a tool that corrects the permissions on several registry
values in Microsoft Windows NT 4.0. The default permissions could allow a
malicious user to gain additional privileges on an affected machine.

After you create the PermittedManagers and ValidCommunities registry keys for the
Simple Network Management Protocol (SNMP) service, any user has permission to
read the contents of the keys. The keys should only be accessible to
administrators. SNMP is not installed on Windows NT 4.0 computers by default.
