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.
